Suppose that p(x,y) represents the production of a two-product firm. The company produces x units of the first product at a cost of c, each and y units of the second product at a cost of C2 each. The budget constraint, B, is a constant given by the following formula. Use the method of Lagrange multipliers to find the value of 2 in terms of Px, Py, C1, and C2. The resulting equation holds for any production function p and is called the Law of Equimarginal Productivity. B=C1X + C2y Choose the correct answer below. Px O A. 2= Py C1 C2 O B. = PX = C1 = Py = C2 O C. 2= Px Py C1 C2 C1 OD. A= C2 PX Py
