Suppose a competitive firm faces a short-run market price of $112, and has a cost function of: C(q) = 4q2 + 10q + 400. Calculate the firm's profit-maximizing quantity. Enter your response rounded to three decimal places: units. Calculate the firm's average cost at this profit-maximizing quantity. Enter your response rounded to two accimal places:]. This firm has economic profits. Based on this firm's profits, we would expect the number of firms in this market to in the long-run. O A. negative, increase O B. negative, decrease O C. postiive, increase O D. positive, decrease For the firm's residual demand curve, given in the form P(q) = a - bq, what is the value b equal to in this market? Assume that this firm is one of the firms that remains in this market in the long-run. Calculate the value for the intercept, a, of its long-run residual demand curve.
