Answer:
Cost of one bush = 23
Cost of one tree = 47
Step-by-step explanation:
Let cost of bushes be x per piece
Let cost of trees be y per piece
First order : 13x + 4 y = 487 ----(1)
Second order : 6x + 2y = 232 -----(2)
multiply (1) by 6 => 78x + 24y = 2922 ----(3)
multiply (2) by 13 => 78x + 26y = 3016 -----(4)
(3) - (4) ==> -2y = -94
y = 47
Substitute y = 47 in (1) ==> 13x + 4(47) =487
13x = 487 - 188
13x = 299
x = 23
