Question

A 6-ounce box of strawberry gelatin costs $0.90 and a 3-ounce box costs $0.42.
What is the difference in cost per ounce between the larger and the smaller boxes?
A. $0.48
B. $0.03
C. $0.04
D. $0.01

Answer 1

To find the cost per ounce for each box, we divide the total cost by the number of ounces.

For the 6-ounce box:
Cost per ounce = $0.90 / 6 ounces = $0.15 per ounce

For the 3-ounce box:
Cost per ounce = $0.42 / 3 ounces = $0.14 per ounce

The difference in cost per ounce between the larger and smaller boxes is:
$0.15 - $0.14 = $0.01

Therefore, the answer is D. $0.01.
