A landscaper planted some trees and bushes in a new subdivision. The first order was for 12 bushes and 15 trees and cost $600. The second order was for 8 bushes and 20 trees and cost $680. Find the price of each tree and bush.
------------
12b + 15t = 600
8b + 20t = 680
------------
Modify:
4b + 5t = 200
4b +10t = 380
-----------------
Subtract and solve for "t":
5t = 180
t = 36 (# of trees)
----
Solve for "b":
4b + 10t = 380
4b + 360 = 380
4b = 20
b = 5 (# of bushes)
