Question

you go to the market to buy fruit.two apples and one banana cost $5. if you buy two apples and three bananas the cost is$7.how much does each apple and each banana cost?

Answer 1

An apple costs $2 and a banana costs $1.

Explanation:

x = cost of 1 apple and y = cost of 1 banana. So:-

2x + y = 5

2x + 3y = 7

Subtract the first equation from the second. We get:-

2y = 2

y = 1

and since 2x + y = 5, 2 x + 1 = 5 and

x = $2.
