Based on this figure, which of the following statements are correct? 8,000 Price, Marginal cost ($) 0 E Quantity of cars, Q At A, the firm makes positive profits. The firm makes the same profit at B and D. O Profit margin is the same at B and D. O The slope of the isoprofit is zero at D. MC Isoprofit A Isoprofit B AC 100A perfectly competitive firm faces the short-run cost schedule shown in Table (a)Calculate average total cost (ATC=TC/Q), marginal cost (MC=ATC/AQ) and marginal revenue (MR-ATR/AQ) for each level of output. The price per unit of output is £16 b) Plot ATC, MC and MR on a graph and mark the profit-maximising output. At what output is profit maximised? c) How much profit/loss is made at the optimum level of output? Assume market price declines to £9 per unit.

- Suppose a perfectly competitive firm is able to sell its product for $8. At its current level of output the firm's average total cost is $6. The firms marginal cost curve intersects its marginal revenue curve at an output of 10 units. The firms experiences a (Hint draw the graph of a firm in perfect competition and input the information) Question 5 options: a) profit of more than $20 b) profit of exactly $20 c) loss of more than $20 d) loss of exactly $20Assume that a firm in a competitive market faces the following cost information. If the market price for this firm's product is $40, calculate the profit maximizing level of output for this firm using marginal analysis. It may help to create your own cost table and fill in columns for Marginal Cost and Average Total Cost based on the Total Cost information below. a.What is the level of profit for this firm at the profit maximizing output? b.To convince yourself that the quantity you found is indeed the profit maximizing quantity, try calculating what the profit would be at the next higher level of output. What did you find? c. What do you predict will happen in this market over the long run?A profit-maximizing firm in a competitive market is currently producing 100 units of output. It has average revenue of $10, average total cost of $8, and fixed cost of $200. What is its profit? What is its marginal cost? What is its average variable cost?

Market demand and supply conditions are indicated in the left-hand panel of the figure attached; the long-run cost curves of a wheat farmer are shown in the right-hand panel. Currently, the market price for wheat is $2 per pound, and at that price, consumers are purchasing 800,000 pounds of wheat per day. Using the graphs attached, answer the following: a. How many pounds of wheat will each farmer produce if they want to maximize profits? b. How many farmers are currently serving the industry (fractional numbers are fine)? c. In the long run, what will the equilibrium price of wheat be? Briefly explain your answer.Refer to the accompanying figure. If the market for doughnuts is perfectly competitive, then assuming this firm can earn enough revenue to cover its variable cost, it should produce: Price (S/doughnut) 0.35 p 0.30 0.25 0.20 0.15 0.10 0.05 0 0 10 20 30 40 50 60 Marginal Cost 70 80 90 Quantity (doughnuts/day) Average Total Cost 50 doughnuts per day. the quantity of doughnuts at which average total cost is minimized. the quantity of doughnuts at which average total cost equals the market price. the quantity of doughnuts at which marginal cost equals the market price.
