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?

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

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.

To find the equation that shows how the cost per student depends on the number of students who attend, we need to understand the relationship between these two variables.

Let's assume that the cost per student remains the same regardless of the number of students attending the movie. In this case, we can divide the total cost of $1,500 by the number of students.

Let's represent the cost per student as 'C' and the number of students as 'N'. The equation that shows how the cost per student depends on the number of students attending the movie is:

C = 1500 / N

In this equation, 'C' represents the cost per student, '1500' represents the total cost, and 'N' represents the number of students. By dividing the total cost by the number of students, we can determine the cost per student.
