Question 620082
Bob has a coin jar containing nickels, quarters, and one dollar coins. He has a total of 44 coins totaling $9.75. And, he has five times as many nickels as he has one dollar coins. How many of each coin does he have? 
----
Quantity Eq::: n  +  q  +  d = 44 coins
Value Eq::::: 5n  +25q  +100d= 975 cents
Quantity Eq::  n  + 0   - 5d  = 0
-----------------------
Solve the system anyway you can to get:
n = 25 
q = 14
d = 5
