I got stuck on monopolist questions. Help is greatly appreciated. This is the information I have, please don't comment on missing data.

Question 20 1 points Save Answer Scenario: Monopoly with Linear Demand A monopolist faces a linear demand of the form P = a-bQ = 500-200 . Their marginal cost ( MC) curve is estimated by the equation MC = 50 +50 . Their cost per unit ( ATC) at their profit- maximizing output ( QM) is $85, while their cost per unit ( ATC) at the competitive market (socially efficient) output ( Qc) is $100.55.
