You can put this solution on YOUR website! A collection of 102 nickels, dimes, and quarters is worth $13.60.
There are 14 more nickels than dimes. How many quarters are there?
------------
Equations:
n + d + q = 102
n = d + 14
5n+10d+25q = 1360 cents
----------------------------
Rearrange:
n + d + q = 102
n - d + 0 = 14
5n+10d+25q=1360
-----------------------
Use any method you know to get:
n = 40 (# of nickels)
d = 26 (# of dimes)
q = 36 (# of quarters)
============================
