<PRE><B>Question 168644</B>
There were equal numbers of nickels and quarters, and twice as many half dollars as quarters. If she found $2.60 in all, how many of each denomination of coin did she find? 
--------------------
n - q + 0 = 0
0 -2q + h  = 0
5n + 25q + 50h = 260
---------------------------
Use any method you know to get:
n = 2
q = 2
h = 4
