Answer:
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
n $x1 n $x2 n $x3
4 20 1 10 2 40 70
5 25 2 20 2,5 50 95
6 30 3 30 3 60 120
7 35 4 40 3,5 70 145
8 40 5 50 4 80 170
9 45 6 60 4,5 90 195
10 50 7 70 5 100 220
11 55 8 80 5,5 110 245
12 60 9 90 6 120 270
x1= 12
x2= 9
x3=6
