Answer :
To find out which bottle of water is a better deal, we need to determine the cost per ounce for the 16-ounce bottle.
Here's how you can calculate the unit rate:
1. Identify the total cost and the volume:
- The total cost for the 16-ounce bottle of water is [tex]$2.40.
2. Determine the volume of the bottle:
- The bottle contains 16 ounces of water.
3. Calculate the unit rate:
- Divide the total cost by the number of ounces to find the cost per ounce.
\[
\text{Cost per ounce} = \frac{\text{Total cost}}{\text{Number of ounces}} = \frac{2.40}{16}
\]
4. Calculate the result:
- When you divide $[/tex]2.40 by 16, the result is [tex]$0.15 per ounce.
Therefore, the unit rate for the 16-ounce bottle of water is $[/tex]0.15 per ounce. This means that each ounce of the 16-ounce bottle costs $0.15. To compare which bottle offers the better deal, you would perform similar calculations for the 28-ounce bottle and compare the unit rates.
