the profit is the difference between the student fees and the studio rental cost
P = (N * F) - C
F = (P + C) / N
I would really try and answer but I don't know how to start or even understand the problem. I would appreciate it if you help
A music teacher runs a guitar class for 20 weeks.
The class meets each week in a rented music studio.
Suppose that:
-It cost the teacher "C" dollars to rent the studio for the 20 weeks.
-The class contains "N" students.
-Each student pays the teacher a single fee of "F" dollars for the course.
-The teacher makes a profit of "P" dollars at the end of the course.
1) Suppose that C=400 and F=70. Write an equation to show how the profit made, P, depends on N, the number of students attending.
2) Write a formula for calculating P when you know C,N, and F.
3) Write a formula for calculating F when you know C, N, and P.
