Joe Bob was amazed when he opened the drawer because it contained 173 coins whose value was $11.25. If all coins were either nickels or quarters, how many of each were in the drawer?
--------
Quantity:: n + q = 173 coins
Value:: 5n+25q = 1125 cents
----------------------------
Modify for elimination::
n + q = 173
n + 5q = 225
-----
Subtract and solve for "q":
4q = 52
q = 13 (# of quarters)
------
n = 173 -13 = 160 (# of nickels)
-------------
