<PRE><B>Question 117369</B>
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
5n+10d+25q= 1360
n = d+14
-------------------
n + d + q = 102
5n+10d+25q= 1360
n - d + 0 = 14
-------------------
Using TI-83 Matrix function I get:
n=40
d=26
q=36
================
