Mike a salvation army bell ringer has 5 fewer quarters than nickels in his cup.Mike has $5.95 in quarters and nickels. How many nickels does he have?
----
Quantity Equation: q = n-5
Value Equation: 5n+25q = 595 cents
----------------------------------
Substitute for "q" and solve for "n":
5n + 25(n-5) = 595
5n + 25n - 125 = 595
30n = 720
n = 24 (# of nickels)
