Question

A 21.5 oz box of cereal sells for $3.44. The same cereal is sold in a smaller 17 oz box for $3.06. How much more per ounce does the 17 oz box of cereal cost than the 21.5 oz box of cereal?

Answer 1

The 17 oz box of cereal costs $0.02 more per ounce than the 21.5 oz box. By calculating the price per ounce for each box ($0.16 for the larger and $0.18 for the smaller), we can determine the difference in cost per ounce.

Step-by-step explanation:

To determine how much more per ounce the 17 oz box of cereal costs than the 21.5 oz box, we first need to calculate the price per ounce for each box. For the 21.5 oz box, we divide the total cost $3.44 by 21.5 oz to get the price per ounce:

$3.44 ÷ 21.5 oz = $0.16 per ounce

For the 17 oz box, we divide $3.06 by 17 oz to get:

$3.06 ÷ 17 oz = $0.18 per ounce

To find out how much more the 17 oz box costs per ounce than the 21.5 oz box, we subtract the price per ounce of the 21.5 oz box from the price per ounce of the 17 oz box:

$0.18 per ounce - $0.16 per ounce = $0.02 more per ounce

Therefore, the 17 oz box of cereal costs $0.02 more per ounce than the 21.5 oz box.
