<PRE><B>Question 177555</B>
Meghan has 100 dollars more than Andrew has. After Meghan spends 20 dollars on groceries, she will have five times as much money as Andrew. How much money does Andrew have?
----------------------------
M = A + 100
M-20 = 5A
-----------------
Rearrange:
M - A = 100
M -5A = 20
----------------
Subtract 2nd from 1st to get:
4A = 80
A = 80
---------------
Substitute to solve for M:
M = 80+100 = 180
========================
