Multiple Choice

Let the inverse demand curve for a monopolist's product be $P = 100 - 2 Q$ and the marginal cost of production be constant at $M C = 10$ . Suppose that the firm considers moving from a uniform pricing strategy to a two-block tariff where the first block provides 15 units at a price of $P _ { I } =$ $\$ 70$ and the second block provides an additional 15 units at a price of $P _ { 2 } = \$ 40$ . How much does the monopolist's profit rise with this scheme?

A) $\$ 225$
B) $\$ 337.50$
C) $\$ 450.50$
