Question

A 32 ounce bottle of water costs $1.60. What is the cost per ounce?

Answer 1

.05 CENTS PER ONCE

Answer 2

160/32

Answer 3

The very words "something per something else" should tell you we have a division problem.

\(Cost\;per\;Ounce = \dfrac{Some\;Cost\;Measure}{Some\;Ounce\;Measure} = \dfrac{$1.60}{32\;oz} = \dfrac{1.60}{32}\;$/oz = \dfrac{160}{32}\;cent/oz\)
