Question

At a discount grocery store, Jessica paid $0.72 for an 8-ounce bottle of spring water. What is the cost of the spring water per ounce?

Answer 1

$0.09 per ounce (9 cents)

Explanation:

This is a division problem. We want to “divide” the larger amount (8-oz.) into the individual unit amounts. So, we take the total amount for the larger quantity and divide it by the number of smaller units that it contains – in this case 8.

0.72/8 = 0.09
