Question 61590
Let x= number of student tickets sold
Then 500-x has to equal the number of general admission tickets sold

Now we know that the amount of $ collected from selling student tickets x($5) plus the amount of $ collected from selling general admission tickets (500-x)($8) must equal the total amount collected ($3475).  Thus, our equation to solve is:

x($5)+(500-x)($8)=$3475  Simplifying, we get:
5x+4000-8x=3475 and
-3x=-4000+3475
-3x=-525
x=175 student tickets
500-x=500-175=325 general admission tickets
