A middle school wants to have its students see a movie at a local theater. The total cost of the theater and movie rental is $1,500. What equation shows how the cost per student depends on the number of students who attend?

Question

I'm not really sure what this question is asking me to do.

Answer 1

The cost per each student depends on the number of students.

If 100 students attend, then we divide 1,500 by 100 = $15. per student.
If 300 students attend, then we divide 1,500 by 300 = $5.00 each.

You need to write an equation showing how the cost per student depends on the number of students who attend.
