Weighted Average Cost Flow Method Under Perpetual Inventory System The following units of a particular item were available for sale during the calendar year: Jan. 1 Inventory 4,000 units at $40 Apr. 19 Sale 2,500 units June 30 Purchase 4,500 units at $44 Sept. 2 Sale 5,000 units Nov. 15 Purchase 2,000 units at $46 The firm uses the weighted average cost method with a perpetual inventory system. Determine the cost of goods sold for each sale and the inventory balance after each sale. Present the data in the form illustrated in Exhibit 5.

Because this market is a monopolistically competitive market, you can tell that it is in long-run equilibrium by the fact thatmr=mc at the optimal quantity for each firm. furthermore, a monopolistically competitive firm's average total cost in long-run equilibrium isless than the minimum average total cost. true or false: this indicates that there is a markup on marginal cost in the market for engines. true false monopolistic competition may also be socially inefficient because there are too many or too few firms in the market. the presence of the externality implies that there is too little entry of new firms in the market.
