Steve and Sons Solar Panels has a production function of Q = 4KL and faces a wage rate of $8 per hour and a rental rate of capital of $10 per hour. Assume that, in the short run, capital is fixed at K = 10. The short-run total cost curve for the firm is TCSR = 100 + 0.20. Find the firm's short-run average total cost (ATCSR), average fixed cost (AFCSR), average variable cost (AVCSR), and marginal cost (MCSR). ATCSR = AFCSR = AVCSR = MCSR =
