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

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
