Final answer:
After calculating the cost per sandwich for both packages, it is determined that the 9 pack of ice-cream sandwiches is the better deal because it costs $0.50 per sandwich, compared to $0.60 per sandwich for the 12 pack.
Step-by-step explanation:
To determine which package of ice-cream sandwiches is the better buy, we need to calculate the cost per ice cream sandwich for each package.
For the 12 pack costing $7.20, the cost per sandwich is calculated by dividing the total cost by the number of sandwiches:
$7.20 ÷ 12 = $0.60 per sandwich
For the 9 pack costing $4.50, the cost per sandwich is:
$4.50 ÷ 9 = $0.50 per sandwich
Since the cost per sandwich is lower for the 9 pack, it is the better deal.
Therefore, the correct answer is:
C. The 9 pack is a better deal because you are paying $0.50 per ice cream sandwich.
