Total no of students* (Tutionfees of student - part of fees used for faculty salary(x))= Total salary of faculty

1790(3700-x)=4629200

x= 1113.85

parts of tution fees used for faculty salary= 37000-1113.85 ~== 2600

Do we really need to use that formula?
I think the answer is straight forward.
4629200/1790=2586.15
Can you tell me why you use that formula?
