For this question, parts A and B are unrelated. A. (5 points) A firm's long-run total cost can be written as LTC = 5000Q - 25Q' + Q and its long-run marginal cost by LMC = 5000 - 50Q + 3Q2. Find the range over which the firm will experience diseconomies of scale. Explain your answer. B. (5 points) A firm has a production function of Q = K x L + K, where the marginal product of labor is MP, = K and the marginal product of capital is MPK = L + 1. The wage rate (W) is $50 per worker and the rental price (R) is $100 per unit of capital. In the short-run, capital (K) is fixed at 5. Find the minimum total cost of production in the short- and long-run if the firm produces 200 units of output
