Answer to Quiz 3 Suppose that a firm’s production function is Q = 25KL, wage = w, rental rate of capital = r. 1. What is the labor demand function? 2. If Q = 100, how many labor would be employed? 3. Find out the total cost function. 1. Cost minimizing condition: MP L / MP K = w / r, That is 25L/25K = w/r, that is , Kr = Lw
