Answer:
The difference in price per ounce of the boxes is $0.03 or 3 cents.
Step-by-step explanation:
Divide each dollar amount by the ounces. The answer to $2.94 divided by 14 is 21 cents. $3.60 divided by 20 is 18 cents. Subtract 18 cents from 21 cents to get 3 cents.
Let D = difference in price per ounce
D = 2.94 ÷ 14 - 3.60 ÷ 20
D = 0.21 - 0.18
D = 0.03 or 3 cents.
