1. ## Are you smart enough to solve this?

How can we go from the given function (6000-9Q)/50 to end up with (120-18Q)/50?

Please write full answer, also if there are any rules used etc I would appreciate an explanation.

You can't, unless there's some other stuff in your problem that needs to be done first. Why not post the entire problem and what you've done?

a. show that the monopolist's revenue function is MR(Q)=120-18Q/50

we are given the following information:

Market structure: monopoly
MC(Q)= 10+Q/25
Q (market demand) = (6000-50P) / 9
TC(Q)= 100+q^2+10q

Brackets required? Why not show as: MR(Q) = (60 - 9Q) / 25

This is NOT a matter of mathematics. We can't go from "MC(Q)"" to "MR(Q)" without knowing relationship between MC and the other quantities you give and MR. In other words, the formulas to be used are from economics, not mathematics.
