1. An umbrella manufacturer has three departments for production. The handle is
produced in the first department, with the second department attaching the fabric to
the handle, and the third department used for packing and distribution. If all umbrellas
produced are similar but can vary by size or color, should the business use a job order or
process cost system?
Process cost system
2. A manager for a new business is trying to decide which type of cost system to account
for the costs incurred during production. The business will manufacture high quality
rugs according to customer specifications. Once the customer specifications are
determined for each order, the company will acquire the inputs needed. Would a job
order or process cost system be best for the manager?
Job order cost system
3. A clothing manufacturer produces ten types of shirts, which are produced on a schedule
set by management. Costs incurred in the production facility in a day are allocated to
the type of shirt produced on that day. Is the company using a job order cost system or
process cost system?
Process cost system
Strategy: Process cost systems are used when all finished goods in a batch are exactly
the same. Since all goods will require the same inputs, the costs are allocated to the
entire amount produced, which will then be allocated by the number of goods.

6. During the period, the Production Department of Shooz Manufacturers incurred
$31,600 in direct materials cost and $13,260 in conversion costs. Using the information
found in Exercise 5, calculate the direct materials and conversion costs per equivalent
unit (EU).
Direct materials cost per EU = $31,600/7,900 EU = $4.00
Conversion cost per EU = $13,260/6,630 EU = $2.00
7. Use the information determined in Exercises 4-6 to calculate the amount of direct and
conversion costs to be allocated to the units transferred to Packaging and the ending
inventory in process. The beginning inventory in process had a cost of $6,200.

11. During the month of March, the company incurred $80,000 of expenses for direct
materials and $40,000 of expenses for direct labor. The company applied $11,250 of
factory overhead to the Mixing Department. Use the information calculated in Exercise
10 to determine the direct materials and conversion cost per equivalent unit (EU).
Round answers to the nearest cent.
Direct materials cost per EU = $80,000/12,500 EU = $6.40
Conversion cost per EU = $51,250/10,250 EU = $5.00

Strategy: Equivalent units are the whole number of units that would be completed if
applied the same amount of direct materials or conversion costs, rather than having a
certain number of partially completed units. If costs are incurred throughout the process,
the beginning inventory in process will be only partially completed as to the costs, like
most conversion costs. However, if the costs are incurred at the beginning of the process,
such as most direct materials are applied at the beginning, then beginning inventory in
process will be fully completed (and not need to incur additional costs in the period).

16. During the month of May, Tables & More allocated $20,000 of direct materials costs and
$13,800 of direct labor to the Assembly Department. The company applied $2,400 of
factory overhead to the Assembly Department. Determine the direct materials and
conversion cost per equivalent unit (EU), using the information determined in Exercise
15.
Direct materials cost per EU = $20,000/4,000 EU = $5.00
Conversion cost per EU = $16,200/5,400 EU = $3.00
Strategy: Direct materials cost per equivalent unit is found by the costs of direct
materials incurred during the period in the department by the number of direct materials
equivalent units. The conversion cost per equivalent units is found by the cost of direct
labor incurred and factory overhead applied during the period in the department by the
number of equivalent units.
17. Use the information calculated in Exercises 9-11 to determine the costs incurred in the
Assembly Department to be allocated to ending inventory in process and the goods
completed and transferred to the Finishing Department. The inventory as of May 1 had
a cost of $6,000.

Strategy: To allocate costs among the various groups, the equivalent units must be
computed for materials and conversion costs since the various groups will incur different
costs (beginning inventory will only require the cost to complete, whereas ending
inventory will incur costs to its percentage completion). The cost per equivalent units can
then be applied to each group (beginning inventory in process, started and completed
units, and ending inventory) to calculate the total costs to allocate.

Strategy: The cost of production report provides the information and breakdown of costs
among beginning inventory in process, the units started and completed during the
period, and the ending inventory in process. The units to be assigned costs and
equivalent units should be calculated in the first portion. The second portion should
include determining the cost per equivalent unit and allocating costs to the various
groups by the number of equivalent units in each. As a check, the total costs accounted
for by the department should equal the total costs assigned by the department to ensure
that costs incurred were allocated to the department.

Strategy: Under a process cost system, the cost of direct materials used in a department
should be allocated to the Work in Process in that department, which would increase the
work in process inventory of the department. If indirect materials are used, Factory
Overhead of the department should be increased to show the costs are incurred.
28. During the month of May, employees worked a total of 750 hours, 80% of which was in
the Mixing Department and the remainder in the Packaging Department. If the company
pays employees an hourly rate of $12, prepare the journal entry to record the cost
incurred as of the end of the month.

Strategy: Like materials, cost of direct labor in a department should also increase the
work in process inventory of that department. Any indirect labor costs incurred should be
recorded as a debit to Factory Overhead, which will be applied to the department later.

29. Conversion costs for the month of May in the Mixing Department totaled $9,000,
including the direct labor in Exercise 28. The conversion costs for the Packaging
Department totaled $2,450, also including direct labor. Prepare the journal entry as of
the end of the month to record the application of overhead to the departments.

Strategy: Factory Overhead will increase the Work in Process of a department when
applied. The journal entry to record the application will increase Work in Process (with a
debit) and decrease Factory Overhead (with a credit) for the amount applied to the
department.
30. On May 27, $5,000 of costs was transferred from the Packaging Department to Finished
Goods. The company sold half of the goods on May 31. Prepare the journal entries to
record the transfer to and from Finished Goods.

Strategy: To show transfers of work in process inventory among departments, debit
Work in Process for the department receiving the inventory to record the increase in cost
of inventory and credit Work in Process for the department transferring the inventory to
record the decrease in cost of inventory. If goods are transferred to Finished Goods,
increase the account using a debit, since it is also a type of inventory. Once goods are
sold, show the decrease in inventory with a credit to Finished Goods and an increase in
the expense of the inventory with a debit to Cost of Goods Sold.

31. Use the information below to calculate the direct materials and conversion costs per
equivalent units for the months of July and August to determine which costs should be
investigated further for inefficiencies in the production process. Round answers to two
decimal places. Assume production began on July 1, with no beginning inventory and
2,000 pounds are transferred to finished goods in the first month. During August, 2,900
pounds are transferred to finished goods. At the end of each month, the company has
2,000 pounds still on hand in work in process. With respect to conversion costs, work in
process is 65% completed as of August 1 and 75% completed as of August 31. All direct
materials are added at the beginning of the production process.

32. Use the cost of production reports for the months of August and September to prepare
a comparison of expenses on a per-unit basis, showing changes in percentages. Round
percentages to one decimal place. Determine which costs should be investigated further
for inefficiencies.

The increase in cost of repairs and cleaning should be investigated. Although the
decrease in cost of materials is favorable, managers may need to inquire about the
change since the change in quality of materials may be causing the increase in repairs
and cleaning.

33. Using the information shown below, calculate the yield for August and September.
Round answers to two decimal places. Determine if the change is favorable or
unfavorable.

The increase in yield is a favorable change, showing less waste.
Strategy: A change in cost can be determined by the change in cost per equivalent units
or by finding the cost per unit produced using a production report. An increase in cost
per unit would be unfavorable because the company is incurring more costs to produce
the same good, while a decrease in cost per unit would be favorable since the company
has found a way to produce the good without incurring as much in costs. However,
managers should ensure that decreases in costs are not causing costs to increase
elsewhere, such as the result of poor quality of materials. An increase in the yield is
favorable because it shows that the company is producing more goods per the amount
put into production by reducing waste and scrap.
34. Determine if each of the following descriptions is a characteristic of a just-in-time
production process.
a. Cross-training employees to perform many functions in the department
Yes
b. Goods move through the production process as the company has the inputs
needed
No
c. Decreased maintenance and repairs, increase in product quality
Yes

35. A computer manufacturer produces finished goods once an order from a customer is
received. The goods begin in the Hardware Center, where the entire internal component
is built before moving the goods and materials to the Keyboard Center. In the Keyboard
Center, the keyboard and its functions are built and tested. The final stage is the
Finishing Center, in which the employees add the last components, test the computer,
and prepare it for delivery. Would this be considered a traditional or just-in-time
production process?
Just-in-time
36. On March 5, 2015, a backpack manufacturer has a large number of employees missing
from the Assembly Department. Although the Assembly Department will have lower
production for the day, the preceding departments in the production process continue
to produce at their maximum capacity in case the departments will have lower
production in the future. Would this be considered a traditional or just-in-time
production process?
Traditional
Strategy: Manufacturers cross-train employees under a just-in-time production process
so that the employees have a better understanding of the process and also increase
production (if a piece of equipment breaks, or another employee is out for the day). Justin-time production “pulls” goods through the process as needed, rather than “pushing”
goods through, as in a traditional process. Only producing goods as needed reduces
storage costs because the goods will be immediately transferred from one department
to the next.
