Tax, Tip, and Discounts-OH MY!
7th Grade Project
Mrs. Egbert
Part I-Tax and Tip
 Get a menu from a restaurant you go to. You may either get a take out menu,
which are usually available at the counter of most restaurants, or you may
search for a menu online.
 Pretend you and your family are going to eat at this restaurant. What is each
person going to order? Make a detailed list of all orders and their prices.
Follow the example below:
Person 1 Order
Diet Coke
French Onion Soup
Chicken Caesar Salad
Apple Pie
Coffee

Calculate the total cost of your bill. You may either do the calculations by
hand or you may use Microsoft excel. We will be going to the computer lab
on October 21st. I will show you how to enter the data in Excel and use
formulas, but you must have your information before then (see Rubric)
Next calculate the tax you would pay on your bill based on the 7% New
Jersey sales tax.
You would also like to leave the waiter or waitress a 20% tip. Calculate the
cost of the tip you are going to leave.
Calculate the total cost of your bill with tax and tip.
Part II-Discounts
 Find an item (clothing, electronics, toys, etc.) you would really like to buy.
The item should be greater than $20 You may either look through a catalog,
online store, newspaper circular, etc. You will need to bring proof of the item
in with your project.
 Pretend the item will be on sale for 30% off the original price; calculate the
discount.
 Calculate how much you will pay for the item once the discount is applied.
 Let’s say this item is bought in New York where the tax on most items
including clothing (there is no tax on clothing in New Jersey) is 8.5%.
Calculate the cost of the item with tax.
 You are planning to buy this item by yourself, you have $5 saved, and you will
receive $5 a week in allowance. Write an equation that will help you
determine how many weeks you will need to save for this item.
