Can someone help. “At the market you can buy 5 bags of apples for $23.60. At the orchard you can get 7 bags of apples for $32.76. Which is the better deal?”

Answers

Answer:

7 for $32.76

Step-by-step explanation:

23.60/5 is $4.72

32.76/7 is $4.68

Answer: $4.72

Step-by-step explanation:

To solve this problem we need to find the unit price of a bag of apples(one bag)

Thus, simply do 23.60/5 to get 4.72 and 32.76/7 to get 4.68.  Because 4.68 < 4.72, the orchard is a better deal.
