If a monopolist's demand curve can be expressed as Q(P) = 96 - 4P, where P and Q denote per-unit price and demand/output, respectively, then the corresponding marginal revenue curve is MR(Q) = 24 - 0.5Q. If the monopolist's marginal cost curve is given by 2.5Q, what is the profit maximizing combination of price and output, respectively?
