Now consider an alternative market structure where there is only one refined cobaltcube producer. This firm acts as a profit-maximizing monopolist. Assume that the monopolist's marginal cost curve is MC(Q) = 25 + 0.1Q, where Q is measured in thousands of cubes. Market demand for cobalt cubes is once again PD(Q) = 50 - 2Q5. The monopolist's marginal revenue is MR(Q) = 50 - 4Q52. a. What is the market equiLiBrium quantity of refined cobalt cubes sold by the monopolist, and what is the price per cube charged? b. At this output level, What is the monopolist's producer surplus? c. What is consumer surplus?
