Answer:
15-ounce package is the best buy.
Step-by-step explanation:
In order to find the best-buy we have to calculate the price per ounce.
So,
For 7-ounce package:
Price =2.45$
Unit price for 7-ounce:
[tex]\frac{2.45}{7} = 0.35\$[/tex]
For 15-ounce Package:
Price: $4.95
Unit price for 15-ounce:
[tex]\frac{4.95}{15} = 0.33\$[/tex]
For 26-ounce Package:
Price: $8.84
Unit price for 26-ounce:
[tex]\frac{8.84}{26} = 0.34\$[/tex]
As we can see that the least unit price is for 15 ounce pack i.e. 0.33 per ounce so,
15-ounce package is the best buy.
