Clear my choicearrow_forwardWhy does a firm in perfect competition produce the quantity at which marginal cost equals price? In a perfectly competitive market, the price of a handsaw is $25. When a firm maximizes its profit, it produces 6 handsaws a day. Draw the marginal revenue curve. Label it. Draw the marginal cost curve that illustrates the profit-maximizing output. Label it. Draw a point at the profit-maximizing output and price. A firm produces the quantity at which marginal cost equals price because when marginal cost is greater than price, the firm O A. can increase economic profit by producing 1 less handsaw O B. is maximizing economic profit OC. is at its shutdown point O D. can increase economic profit by producing 1 more handsaw 50- 45- 40- 35 30- 25- 20- 15- 10- 5 0- 0 Price (dollars per handsaw) 10 Quantity (handsaws per day) >>> Draw only the objects specified in the question.arrow_forward. A perfectly competitive, profit maximizing firm earns zero economic profit in the long run. The firm's total cost is: TC = a + bQ?. Use only the cost curve given. a.

- Below is a graph of price and cost curves for a perfectly competitive firm that explains the profit/loss states of three different price levels. a. At what quantity and price the firm will maximise its profit and calculate the total revenue, cost and profit. b. At what quantity and price the firm will minimise its loss and calculate the total revenue, cost and minimum loss. c. At what price the firm will decide to shut down firm and justify your answer.arrow_forwardDiscuss the shape of the long-run supply curve in a perfectly competitive market. The long-run supply curve is A. an upward-sloping line equal to the sum of the portion of each firm's marginal cost curve that is above minimum average variable cost. B. a horizontal line equal to the minimum point on the typical firm's average total cost curve. C. an upward-sloping line equal to the sum of each firm's marginal cost curve. D. a horizontal line equal to the minimum point on the typical firm's average variable cost curve. E. an upward-sloping line equal to the sum of each firm's supply curve. Suppose that the perfectly competitive market illustrated in the graph to the right is initially in long-run equilibrium (at P₁) and then there is a permanent decrease in the demand for the product (to D₂). Show how the market adjusts in the long run. 1.) Use the line drawing tool to add either a new demand curve or a new supply curve showing the market in long-run equilibrium.
