Calculate the profit-maximizing price, total revenue, total royalty payments, firm profit, and deadweight loss.

A percentage royalty plan, where the investor receives 20 percent of the firm's revenue each period (0.20 x (160 x $480) = $15,360). Consider an investor interested in a firm whose inverse demand equals: P = 800 - 2Q. The firm's marginal cost of output is constant and equals $160 per-unit. The profit- maximizing firm produces 160 units in each period (MR = 800 - 4Q = 160; so Q = 160, and sets its price at $480 (800 - 2x160)). At this level of output, firm revenue equals $76,800 (160 x $480) and its profit equals $51,200 (($480 - $160) x 160).
