Responses
28 oz. of cereal for $4.29
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
To determine the best buy, we need to compare the price per ounce of each cereal.
For the first option, the price per ounce is 4.29 / 28 = $0.1532 per ounce.
For the second option, the price per ounce is 4.59 / 32 = $0.1434 per ounce.
For the third option, the price per ounce is 4.79 / 36 = $0.1331 per ounce.
For the fourth option, the price per ounce is 3.59 / 24 = $0.1496 per ounce.
Therefore, the best buy would be the third option, 36 oz. of cereal for $4.79, with a price per ounce of $0.1331.
