The demand for a product sold by a monopolist is described by the following equation Q = 125 - P where Q is the quantity and P is the price per unit. The total cost function of the monopolist is TC = 10 + 5Q + 202. A. Write down, the Marginal Revenue, Marginal Cost and Profit of the firm as functions of the quantity B. Find the firm's profit-maximizing quantity and price and calculate the maximum profit C. Find the equilibrium quantity, price and profit if the firm is forced to behave like a perfectly competitive industry D. Assume satisficing behaviour where the managers of the firm must satisfy the constraint that profits equal 20% of the Revenue, 7to=0.2xTR. Identify the quantity, price and profit which correspond to the latter constraint
