Abank teller has some five-dollar bills and some twenty-dollar bills. the teller has a total of 32 bills. the total value of the money is $430.00. find the number of five-dollar bills that he has

write and solve an equation

14 five-dollar bills

Step-by-step explanation:

Let

x> the number of five-dollar bills

y> the number of twenty-dollar bills

we know that

x+y=32 > y=32-x > equation A

5x+20y=430 > equation B

Substitute equation A in equation B and solve for x

5x+20(32-x)=430

5x+640-20x=430

20x-5x=640-430

15x=210

x=14 five-dollar bills

Find the value of y

y=32-x > y=32-14=18 twenty-dollar bills
