The statement, a monopolist maximizes profits where marginal revenue equals marginal cost, is true.
A monopolistic market is where one firm produces one product. A key characteristic of a monopolist firm is that it's a profit maximizer. In this market there is no competition, as the monopolist controls the price and quantity demanded.
A monopolist maximizes profit at the level of output where marginal revenue equals marginal cost. Since it is a monopoly, the marginal revenue is almost always lower than price since a monopoly can artificially limit supply to boost prices, and thus which leads to profit.
