➷  Work out the original area:

(5 x 18) / 2 = 45cm^2

Increase/decrease the changed values:

18 x 0.7 = 12.6

5 x 1.2 = 6

New area:

(12.6 x 6) / 2 = 37.8cm^2

Calculate percentage change:

((45 - 37.8) / 45) x 100 = 16

16% decrease

1. Three apples, a, and two peaches, p, sell for $1.25.
Simora [160]

Answer:

$0.25

Step-by-step 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)
