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

Answer 1

To determine the best buy, we need to calculate the unit price for each cereal.

The unit price is calculated by dividing the cost by the number of ounces.

For the first option: 4.29 / 28 = $0.15 per oz
For the second option: 4.59 / 32 = $0.14 per oz
For the third option: 4.79 / 36 = $0.13 per oz
For the fourth option: 3.59 / 24 = $0.15 per oz

Based on the unit price, the third option of 36 oz. of cereal for $4.79 is the best buy, as it has the lowest unit price at $0.13 per oz.
