Using proportions, it is found that the better deal, on a per ounce basis, is given by:
- A a 30 oz. box of Tasty Wheats for $4.20
- To find the better deal, we use <em>proportions </em>to find the cost per ounce, that is, dividing the cost per the amount of ounces. The <em>better deal </em>is the one with the smaller cost per ounce.
For each option, the costs per ounce are given by:
- A a 30 oz. box of Tasty Wheats for $4.20:
- B a 24 oz. box of Cherry Oats for $3.60
- C a 42 oz. Box of Giganto Flakes for $6.30
- D a 42 oz. Box of Giganto Flakes for $6.30
Due to the <em>smaller cost</em>, option A is the better deal.
