Question

A 2-pint bottle of mouthwash costs $8.00. What is the price per fluid ounce?

Answer 1

To find the price per fluid ounce, we need to convert the volume from pints to fluid ounces and then divide the total cost by that volume.

1. **Convert pints to fluid ounces**:
There are 16 fluid ounces in a pint. Therefore, a 2-pint bottle contains:
\[
2 \text{ pints} \times 16 \text{ fluid ounces/pint} = 32 \text{ fluid ounces}
\]

2. **Calculate the price per fluid ounce**:
The total cost of the mouthwash is $8.00. Thus:
\[
\text{Price per fluid ounce} = \frac{\text{Total cost}}{\text{Total fluid ounces}} = \frac{8.00}{32}
\]
\[
\text{Price per fluid ounce} = 0.25
\]

The price per fluid ounce is **$0.25**.
