Step-by-step explanation:
let number of brand new busses = x
let number of secound hand busses = y
from first condition
x + y = 20
x = 20 - y
cost of brand new busses = 8000x
cost of scount hand bus = 3500y
8000x + 3500y = 160000
8000( 20 - y ) + 3500y = 106000
160000 - 8000y + 3500y = 106000
-4500y = -54000
y = 12
x = 20 - y
x = 8
