(1 point)
A. $0.48
B. $0.03
C. $0.04
D. $0.01
To find the cost per ounce for the 6-ounce box, we divide the total cost by the total ounces: $0.90 / 6 oz = $0.15/oz.
To find the cost per ounce for the 3-ounce box, we divide the total cost by the total ounces: $0.42 / 3 oz = $0.14/oz.
The difference in cost per ounce between the larger and smaller boxes is $0.15/oz - $0.14/oz = $0.01/oz.
Therefore, the correct answer is:
D. $0.01
