<PRE><B>Question 9414</B>
Let x = number of $500 bills
500 - x = number of $100 bills


500x + 100(500 - x ) = 50000
500x + 50000 - 100x = 50000
400x + 50000 = 50000
400x = 0
x= 0


No $500 bills, but all 500 bills are $100 bills, for a total of $50,000.


We should have thought of that before we came up with this fancy equation.  Oh, well. . .
