Answer 1

To determine the best buy, we need to calculate the cost per ounce for each cereal option.

For the first option, the cost per ounce is $4.29/28 oz = $0.1532/oz.

For the second option, the cost per ounce is also $4.29/28 oz = $0.1532/oz.

For the third option, the cost per ounce is $4.59/32 oz = $0.1434/oz.

For the fourth option, the cost per ounce is $4.59/32 oz = $0.1434/oz.

For the fifth option, the cost per ounce is $4.79/36 oz = $0.1331/oz.

Finally, for the sixth option, the cost per ounce is $3.59/24 oz = $0.1496/oz.

Comparing the cost per ounce, the best buy is the fifth option of 36 oz. of cereal for $4.79.
