11. A monopolist is faced with the following cost and revenue curves: (a) What is the maximum-profit output? E 80 MC (b) What is the maximum-profit price? 70 (c) What is the total revenue at this price 80 and output? 50 (d) What is the total cost at this price and AC output? 40 (e) What is the level of profit at this price 30 and output? 20 AR (f) If the monopolist were ordered to produce 300 units, what would be the 10 market price? 100 200 300 403 500 600 (@) How much profit would now be made? -10 (h) If the monopolist were faced with the MR -20 same demand, but average costs were constant at $60 per unit, what output Quantity would maximise profit? What would be the price now?. How much profit would now be made? (k) Assume now that the monopolist decides not to maximise profits, but instead sets a price of f40. How much will now be sold? (1) What is the marginal revenue at this output? (m) What does the answer to (1) indicate about total revenue at a price of $40? (n) What is the price elasticity of demand at a price of $40? (You do not need to do a calculation to work this out: think about the relationship between MR and TR.)
