Question

A wallet contains 23 bills.all the bills are 1$ bills and 5$ bills. there are 7 more 1$ bills than 5$ bills how much money does the wallet contain

Answer 1

Let x = the number of $5 bills

Let x + 7 = the number of $1 bills

x + x + 7 = 23

2x = 16

x = 8

x + 7 = 15

8(5) = $40

15(1) = $15

Total = $55
