A change machine at an arcade gives change for $1 bills and $5 bills. On Monday, 200 bills were inserted into the machine. The total value of the bills was $300  How many $1 bills were inserted into the machine on Monday?

Let  n  = the  number  of $1  bills

 

So......200 - h   =  the  number  of  $5 bills...so we  have  this equation

 

1*n + (200-n) *5   =  300

 

1n  + 1000  - 5n  =  300

 

Can you take it from here  ???
