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?
To find the cost per ounce for the 6-ounce box, divide the total cost by the number of ounces:
Cost per ounce for the 6-ounce box = $0.90 / 6 = $0.15 per ounce
To find the cost per ounce for the 3-ounce box, divide the total cost by the number of ounces:
Cost per ounce for the 3-ounce box = $0.42 / 3 = $0.14 per ounce
The difference in cost per ounce between the larger and the smaller boxes is:
$0.15 - $0.14 = $0.01 per ounce
Therefore, the difference in cost per ounce between the larger and the smaller boxes is $0.01.
