28 oz. of cereal for $4.29
32 oz. of cereal for $4.59
32 oz. of cereal for $4.59
36 oz. of cereal for $4.79
36 oz. of cereal for $4.79
24 oz. of cereal for $3.59
24 oz. of cereal for $3.59
To determine the best buy, we need to compare the cost per ounce for each cereal option.
Option 1: 28 oz. of cereal for $4.29
Cost per ounce: $4.29 / 28 oz. = $0.1532 per ounce
Option 2: 32 oz. of cereal for $4.59
Cost per ounce: $4.59 / 32 oz. = $0.1434 per ounce
Option 3: 36 oz. of cereal for $4.79
Cost per ounce: $4.79 / 36 oz. = $0.1331 per ounce
Option 4: 24 oz. of cereal for $3.59
Cost per ounce: $3.59 / 24 oz. = $0.1496 per ounce
Based on the calculations, the best buy would be the option with the lowest cost per ounce. In this case, the best buy would be the 36 oz. of cereal for $4.79 as it has the lowest cost per ounce ($0.1331 per ounce).
so what is the right answer
The best buy among the given options is:
36 oz. of cereal for $4.79
