Question

9. (10 points) Suppose you and your friend go to a fruit stand which sells apples and bananas (by item

and not weight). You buy 3 bananas and an apple and your friend buys two apples and 2 bananas. Your
receipts show that you spent 2 dollars and your friend spent 3 dollars. How much money would I need
to buy 2 bananas and 7 apples?

Answer 1

To buy 2 bananas and 7 apples, you would need $3.90.

Step-by-step explanation:

To find out how much money is needed to buy 2 bananas and 7 apples, we need to first determine the cost of each fruit.

From the given information, 10 apples cost $5.00, so 1 apple costs $5.00 / 10 = $0.50.

From the given information, 12 bananas cost $2.40, so 1 banana costs $2.40 / 12 = $0.20.

To calculate the total cost, multiply the number of bananas (2) by the price of 1 banana ($0.20) and multiply the number of apples (7) by the price of 1 apple ($0.50).

Total cost = (2 bananas x $0.20 per banana) + (7 apples x $0.50 per apple)

Total cost = $0.40 + $3.50

Total cost = $3.90

Therefore, you would need $3.90 to buy 2 bananas and 7 apples.
