There are 720 apple trees, peach trees and lemon trees altogether in an orchard. The number of apple trees is 2 times the number of lemon trees. The number of peach trees is half the number of apple trees. Find the number of each type of fruit trees in the orchard.

1 answer

A = 2 L
P = A/2 so A = 2 P
so for starters P = L = A/2
P + A + L =720
A/2 + A + A/2 = 720
2 A = 720
A = 720/2
now go back and get P= L = 720/4
