Elizabeth cashed a check for $199. The teller gave her six twenty-dollar bills, x ten-dollar bills, and nineteen one-dollar bills. Find the value of x.

Respuesta :

Answer:

[tex]x=6[/tex]

Step-by-step explanation:

We can set up an equation with the information given:

[tex]6[/tex] · [tex]20+x[/tex] · [tex]10+19[/tex] · [tex]1=199[/tex]

We can simplify that to:

[tex]120+10x+19=199[/tex]

Which is, simplified further:

[tex]139+10x=199[/tex]

If we subtract 139 from both sides of the equation, we will get:

[tex]10x=60[/tex]

Thus, [tex]x=6[/tex].

Hope this helps :)
