➷ 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

Step-by-step explanation:
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)
