4. All sneaker firms have the same cost curves. Long-run average cost curve: AC = -150 + Sq + 2,025/q Long-run total cost curve: TC= 2,025 150q + qu Long-run marginal cost curve: MC = -150 + 10q Market demand for coats: QD = 43,998 500P q = number of coats sold by firm per hour P = price per coat 4a. Calculate the long-run equilibrium price and how many sneakers each individual owner will sell per hour. 4b. Calculate how many rms there are? 4c. If fixed costs increase by 500, calculate how many sneakers each rm will now produce per hour
