Answer 1

Given:

A certain shampoo is available in two sizes.

The first size: A 12.6-ounce bottle costs $2.37

so, the unit rate is:

$=\frac{2.37}{12.6}=0.188$

so, Unit price for the 12.6-ounce bottle: $0.188 per once

The second size: A 25.3-ounce bottle costs $5.24

so, the unit rate is:

$=\frac{5.24}{25.3}=0.207$

So, Unit price for the 25.3-ounce bottle: $0.207 per ounce

So, the better buy is: The 12.6-ounce bottle.
