Question

1. Three apples, a, and two peaches, p, sell for $1.25.

Five apples and 1 peach sell for $1.50. What is the
cost of one apple?

Answer 1

$0.25

Explanation:

You can use systems of equations to solve this.

3a+2p = 1.25

5a+p = 1.5

Multiply the second equation by 2.

3a+2p = 1.25

10a+2p = 3

Subtract the bottom from the top

-7a= -1.75

Divide by -7

a= 0.25

Each apple is $0.25 (in this case, the peach also costs $0.25)
