Final answer:
To determine the best buy, compare the cost per ounce for each package and choose the one with the lowest cost per ounce.
Step-by-step explanation:
To determine which package is the best buy, we need to compare the cost per ounce for each package.
For the 9-ounce package, the cost per ounce is 3.33 divided by 9, which equals approximately 0.37 dollars per ounce.
For the 14-ounce package, the cost per ounce is 5.46 divided by 14, which equals approximately 0.39 dollars per ounce.
For the 26-ounce package, the cost per ounce is 9.88 divided by 26, which equals approximately 0.38 dollars per ounce.
Therefore, the 9-ounce package has the lowest cost per ounce, making it the best buy.
