The demand curve for a profit-maximizing monopolist can be described by the equation Q=200-PQ=200P. The marginal revenue curve for the monopolist is described by the equation MR=200-2QMR=2002Q. The marginal cost associated with producing this good is constant at $50.

The profit maximizing qaunity is either 50 or 75 or 100 0r 125 or 150 and the profit maximizing price is $50 or $75, 0r $100 or $125 or $150?
