Question 359878
There are 4 times as many shrubs as there are trees. Altogether, there are 40 trees and shrubs. How many trees are there? How many shrubs are there? 
---
Equations:
s = 4t
s + t = 40
----
Substitute for "s" and solve for "t":
4t+t = 40
5t = 40
t = 8 (# of trees)
---
Since s = 4t, s = 4*8 = 32 (# of shrubs)
