A certain brand of coffee comes in 2 sizes. A 10.5 ounce package costs $2.99. A 29.3 ounce package costs $7.98. Find the unit price for each size. Then state which size is the better buy based on the unit price. Round your answer to the nearest cent.

Answer 1

To find the unit price for each size, we divide the cost by the number of ounces:

For the 10.5 ounce package: $2.99 / 10.5 oz = $0.285714285714286 per ounce

For the 29.3 ounce package: $7.98 / 29.3 oz = $0.272115897967212 per ounce

Rounded to the nearest cent, the unit price for the 10.5 ounce package is $0.29 per ounce, and the unit price for the 29.3 ounce package is $0.27 per ounce.

Based on the unit price, the 29.3 ounce package is the better buy.
