Answer :
Final answer:
The 12 oz. can is the better deal as it has a lower cost per ounce compared to the 20 oz. bottle.
Explanation:
To determine which is the better deal, we need to compare the cost per ounce of the 12 oz. can and the 20 oz. bottle of cola.
Cost per ounce for the 12 oz. can = $0.72 / 12 oz. = $0.06/oz.
Cost per ounce for the 20 oz. bottle = $1.40 / 20 oz. = $0.07/oz.
Therefore, the 12 oz. can is the better deal as it has a lower cost per ounce compared to the 20 oz. bottle.
