Sagot :

Answer:

5x + 10y + 20z = 115

5x + 10y = 75

20z + 75 = 115

Explanation:

Given that the wallet contained 11 bills in total

The total value of the bill was $115

The amount of the $5 and $10 was $75

If there was x $5 bills, y $10 bills, and z $20 bill

We have the following equations:

5x + 10y + 20z = 115

5x + 10y = 75

20z + 75 = 115

These are the three equations
