A multi-plant monopolist faces the inverse demand P Q = 30 . The first plant has a marginal cost of 1 1 MC Q = 2 and the second plant has a marginal cost of 2 2 MC Q = 2 . Illustrate in a Figure the inverse demand, the different marginal costs, the total production, and the plant level production. (Just illustrate the different functions without attaching specific production units for different plants; no calculation required!)
