Number of $5 bills= 12

Number of $10 bills= 9

Number of $20= 6

Explanation:

Giving the following information:

Total deposit= $270

$5 bills are three more than the number of $10 bills.

The number of $20 bills is half the number of $5 bills.

x1= number of $5 bills

x2= number of $10 bills

x3= number of $20 bills

x1=3+x2

x3=x1/2

The function to calculate the number of bills is:

Total number of bills= (3+x2)*$5 + x2*$10+ (x1/2)*$20
