a.If the demand curve facing a monopolist (which sells its product in one market) fits the equation Price equals 96 minus three times the Quantity, the monopolist produces in one plant where Marginal Cost equals six times the quantity produced in that plant and in another plant where Marginal Cost equals three times the quantity produced in that plant, the profit-maximizing price for the product is 48.

Is this statement true? and if so how many units should the firm produce to maximise profit.
