Michael has a jar filled with one and five dollar bills. The jar contains 32 bills and totals $108. How many bills of each type does he have?

Answer 1

x + y = 32

x + 5y = 108

subtract the 1st equation from the 2nd to get

4y = 76

y = 76/4 = 19 five dollar bills

x = 32-19 = 13 one dollar bills

13+5(19) = 13 + 95 = 108
