Vincent has $5 bills and $20 bills. He has a total of 24 bills and the total amount is $210. How many $5 bills does he have? Help pls

18

Step-by-step explanation

Let's say that  the amount of 5 dollar bills is x and 20 dollar bills is y, with this we can make an equation

x + y = 24

With that we can say that

5x + 20y = 210

Because that is how much each bill costs and the amount of which will equal a total of 210

Solve this systems of equations using elimination

5x + 5y = 120

-5x - 20y = -210

-15y = -90

y = 6

Plug in y = 6 to the first equation.

x + 6 = 24

x = 18

18 is the amount of 5 dollar bills.
