Question

At the local grocery store, a 16-ounce bottle of apple juice costs $3.20. What is the cost of the apple juice per ounce?

Answer 1

You are to calculate the "unit cost" here.

Divide $3.20 by 16 oz:

$3.20
Unit cost = ------------- = $0.20/oz = twenty cents per ounce
16 oz

Answer 2

$3.20 / 16 oz = 0.2 = $ 0.20 / oz
