A 6-ounce box of strawberry gelatin cost $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? (1 point)
A. $0.48
B. $0.03
C. $0.04
D. $0.01
To calculate the cost per ounce for each box, divide the total cost by the total weight:
Cost per ounce for 6-ounce box: $0.90 / 6 = $0.15 per ounce
Cost per ounce for 3-ounce box: $0.42 / 3 = $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
