A group of students are going to attend a concert. The cost per person varies inversely and depends on the number of people attending the concert. It will cost $75 per ticket if 2000 people attend. How much will the tickets be if 5000 people attend?

$30

You can get this by setting up the equation below. 

75 = [tex] \frac{x}{2000} [/tex]

Then you would cross multiply to see what the base cost is. Then you could divide that number by the new number, 5000, to get the new cost.
