(1 mark) Consider a monopolist who produces a good at zero cost and faces the following inverse demand function: Q 60, where P and Q denote price and quantity respectively. In what follows, round your answers to three decimal places if necessary. Monopolist's profit is maximised at P Q (1 mark) Suppose everything is the same as in part (a) except the inverse demand function - where the inequalities have just switched places. The new inverse demand function is 150 - Q, Q > 60, P = 270 - 3Q, Q 5 60. Monopolist's profit is maximised at
