A bank Teller has a total of 56 five dollar bills in her cash drawer the value of the bill is 520 if X represents the number of $20 bills and Y represents the number of five dollar bills determine the number of $20 bills are in her drawer about solving systems

There are 16 $20 bills in the drawer

Step-by-step explanation:

Since we have a total of 56 bills;

x + y = 56 •••••••(i)

total of the $20 bills will be 20(x) = $20x

Total of the $5 bills will be 5(y) = $5y

adding together gives $529

5y + 20x = 520 •••••••(ii)

From the first equation;

y = 56 - x

Put this in the second equation

5(56-x) + 20x = 520

280 - 5x + 20x = 520

15x = 520-280

15x = 240

x = 240/15

x = 16

the answer is a

step-by-step explanation:

39.00 x 24 = total installment price

carrying installment price - cash price
