A collection of nickels and quarters is worth $18.50. there are 118 coins and all. How many are nickels and how many are quarters?
------
Quantity:: n + q = 118 coins
Value:: 5n + 25q = 1850 cents
---------------------------------
Modify for elimination:
n + q = 118
n + 5q = 370
----------
Subtract and solve for "q"::
4q = 252
q = 63 # of quarters
-----
n = 118-q = 118 - 63 = 55 (# of nickels)
--------
