let x = the number of $100 bills

x + 46 = the number of $50 bills

7x = the number of $20 bills

100x + 50(x + 46) + 20(7x) = 9550

100x + 50x + 2300 + 140x = 9550

290x + 2300 = 9550

290x = 7250

x = 25

There are 25 one hundred dollar bills, x + 46 = 25 + 46 = 71 fifty dollar bills, and 7x = 7 * 25 = 175 twenty dollar bills
