1.6 Practice
Calculate the unit rates for each item.
1. A bottle of fruit juice contains 63 ounces and costs $2.25. Calculate the unit rate showing ounces per
dollar and the unit rate showing dollars per ounce.
2. A dozen scones cost $5.95. Calculate the unit rate showing scones per dollar and the unit rate
showing dollars per scone.
3. A 2.5 pound bag of apples costs $2.99. Calculate the unit rate showing pounds of apples per dollar
and the unit rate showing dollars per pound of apples.
Estimate the unit rates of each item to determine which is the better buy.
4. A 4 liter bottle of laundry detergent costs $7.99. A 6.5 liter bottle of laundry detergent costs $16.99.
Which is the better buy?
5. A 64 ounce bottle of apple juice costs $1.99. A 140 ounce bottle of apple juice costs $2.80. Which is
the better buy?
6. An 18 ounce jar of peanut butter costs $1.29. A 64 ounce jar of peanut butter costs $3.80. Which is
the better buy?
