You are back on the HOA board. The time has come to buy more trees and bushes for the neighborhood park.
The first order was for 24 bushes and 16 trees and the bill totaled $3960.
24b + 16t = 3960

The second order was 12 bushes and 32 trees and the bill totaled $5220.
12b + 32t = 5220

Multiply thru the 2nd eq. by 2:
24b + 16t = 3960
24b + 64t = 10440
---
Subtract and solve for "t":
48t = 6480
t = 135 (# of trees purchased)
---
solve for "b":
24b + 16*135 = 3960
24b = 1800
b = 75 (# of bushes purchased)
