encient? Suppose that a company operates in the monopolistically competitive market for electric razors. The following graph shows the demand curve, marginal revenue (MR) curve, marginal cost (MC) curve, and average total cost (ATC) curve for the firm. Place a black point (plus symbol) on the graph to indicate the long-run monopolistically competitive equilibrium price and quantity for this firm. Next, place a grey point (star symbol) to indicate the minimum average total cost the firm faces and the quantity associated with that cost. 3; 100 50 90 80 88 + 70 70 60 550 40 PRICE (Dollars per razor) 30 30 10 MC 20 20 0 10 10 ATC +. ?
