- For a perfectly competitive firm, what is the relationship between Price and Marginal Revenue?arrow_forwardRequired information The following figure shows the costs for a perfectly competitive producer: AVC, ATC, MC $46 235 30 25 20 15 10 5 0 MC 10 20 30 40 50 60 70 80 90 100 ATC AVC Output per period Refer to the above figure to answer this question. If the price of the product is $10, what is the profit-maximizing (or loss-minimizing) output?arrow_forwarda.Suppose a perfectly competitive firm can produce10000 bushels of corn a year at an output at which marginal revenue is equal to marginal cost. The market price of corn per bushel is $2. The firm's total costs per year are $30000 and fixed costs per year are $15000. Show and explain which of the following is true: In the short run, this firm should a) Produce 20000 bushels to try to increase economic profit. b) Produce 10000 bushels of corn because, although they are losing money, they are losing less than if they shut down. c)Shut down. d) Continue producing until the price of corn increases. b.A perfectly competitive firm, with MC=q operates in a market character,zed by the following market demand and supply conditions: Demand: Q=20000-100P Supply: Q=100P How much output does this competitive firm produce to maximize profit? Show your work graphically and algebraically.arrow_forward
- Lisa lawn company (LLC) is a lawn mowing business in a perfectly competitive market for lawn moving services. The following tables set out Lisa's costs Quantity(lawn per hour) Total Cost(dollars per lawn) 0 $30 1 $40 2 $55 3 $75 4 $100 5 $130 6 $165 A. If the market price is $30 per lawn, How many lawns per hour does Lisa's LLC now? B. If the market price is 30 per lawn, What is Lisa"s profit in the short run? C. if the market price falls to $20 per lawn, how many lawns per hour does Lisa's LLC now? D. if the market price falls to $20 per lawn, what is Lisa's profit in the short run? E. At What market price will Lisa shut down?arrow_forwardBrody's firm produces trumpets in a perfectly competitive market. The table below shows Brody's total variable cost. He has a fixed cost of $240, and the price per trumpet is $60.-Calculate the average total cost of producing 6 trumpets. Show your work. -Calculate the marginal cost of producing the 11th trumpet. -What is Brody's profit-maximizing quantity? Use marginal analysis to explain your answer. -At the profit-maximizing quantity you determined in part (c), calculate Brody's profit or loss. Show your work. -Brody also produces saxophones at a loss in a perfectly competitive market. Draw a correctly labeled graph for Brody's firm showing the following at a market price of $200. -Brody's profit-maximizing quantity of saxophones -Brody's loss, completely shaded Quantity Total Variable cost 6 $120 7 $145 8 $165 9 $220 10 $290 11 $390arrow_forwardThe following graph plots the marginal cost (MC) curve, average total cost (ATC) curve, and average variable cost (AVC) curve for a firm operating in the competitive market for snapback hats. COSTS (Dollars) 100 100 80 90 80 20 70 70 HD 50 40 30 20 0 11 D 10 O MC Price (Dollars per snapback) 15 15 20 25 55 70 85 201 ATC 0 D AVC O 50 60 70 80 QUANTITY (Thousands of snapbacks) For every price level given in the following table, use the graph to determine the profit-maximizing quantity of snapbacks for the firm. Further, select whether the firm will choose to produce, shut down, or be indifferent between the two in the short run. (Assume that when price exactly equals average variable cost, the firm is indifferent between producing zero snapbacks and the profit-maximizing quantity of snapbacks.) Lastly, determine whether the firm will earn a profit, incur a loss, or break even at each price. □ Quantity (Snapbacks) BO 100 ▼ On the following graph, use the orange points (square symbol) to…arrow_forward
