Answer:

Step-by-step explanation:

x = $5 dollar bills

 y = $10 dollar bills

 x + y = 15

 5x + 10y = 120

5x + 10(15-x) = 120

 5x + 150 - 10x = 120

 -5x = -30

 x = 6, so y = 9

 

There are six $5 bills and nine $10 bills.

Multiples of 5s will only end with 5 or 0.  5 times any odd number will always end with 5 and 5 times any even number will always end with 0
