Part of the proceeds from a garage sale was $455 worth of $5 bills and $20 bills. if there were 6 more $5 bills than 20$ bills find the number of each denomination

Step-by-step explanation:

               Let x = the number of $20 bills.

     Then x + 6 = the number of $5 bills  and

20x + 5(x +  6) = 455

                    x = 17 = number of $20 bills

x + 6 = 17 + 6 = 23 = number of $5 bills

Check:

OK.

.632
