Answer 1

*I’m going to assume that the numbers in the question got typed twice by accident.

To find the cost per ounce for a box, you need to divide the cost of a box by the number of ounces of cereal the box contains.

1.

$5.16 for a 12 ounce box

Cost/Ounces = Cost per ounce

5.16/12 = 0.43

$0.43 per ounce

2.

$6.48 for an 18 ounce box

Cost/Ounces = Cost per ounce

6.48/18 = 0.36

$0.36 per ounce
