Figure: Cost Curves for Corn Producers Price, cost of bushel $30 26 MC 22 18 ATC AVC 14 10 1 3 4 7 Quantity of corn (bushels) Reference: Ref 12-3 (Figure: Cost Curves for Corn Producers) Look at the figure Cost Curves for Corn Producers. The market for corn is perfectly competitive. If the price of a bushel of corn is $10, in the short run, the farmer will produce of corn and earn an ec omic equal to 2 bushels; profit; $0 2 bushels; loss; just more than $80 per bushel 3 bushels; profit; loss, -$15 4 bushels; profit; just less than $80 per bushel
“That segment of a competitive firm’s marginal-cost curve that lies above its average-variable-cost curve constitutes the shortrun supply curve for the firm.” Explain using a graph and words.
A company in a competitive market has fixed costs of $200. A total cost curve is given in the table below. Given the data, answer the questions below. Output: 10 20 30 40 50 60 Total Cost:300 420 560 720 900 1100 a. Given the price is $20, what is the profit-maximizing output? What is the profit? b. Given the price is $20, what will happen in the long run? c. At the long-run equilibrium, what will the price be in the long run? What is the profit-maximizing output? What is the profit of the company? d. Prepare marginal cost schedule cost schedule for the firm.
Suppose the cost of renting a snowy bus were to fall from $30 per hour to $20 per hour. What do you expect would happen in the short-run (stage 1 equilibrium) to (a) the number of cones produced by each snowy bus; (b) total production of cones in the market, and (c) economic profits of snowy bus businesses? Briefly explain (you don't need to do any calculations, just explain inwords).

Use the orange points (square symbol) to plot the short-run industry supply curve for the wheat industry. Specifically, place an orange point at the lowest point of the supply curve and another orange point at the highest point of the supply curve. (Hint: You can disregard the portion of the supply curve that corresponds to prices where there is no output, since this is the industry supply curve. Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.) 2. Place the black point (plus symbol) on the graph to indicate the short-run equilibrium price and quantity in this market.

Given the following Information about a competitive firm's costs, calculate marginal cost and then answer three questions. Instructions: Enter your responses as a whole number. If you are entering any negative numbers be sure to include a negative sign (-) In front of those numbers. Output (Units) Total Cost Marginal Cost 10 $50 11 52 $ 2 12 56 $ 4 13 62 $ 6 14 70 $ 8 15 80 $ 10 16 92 $ 12 17 106 $ 14 18 122 $ 16 19 140 $ 18 a. If the prevailing market price is $12 per unit, how much should the firm produce? 16 units b. How much profit will it earn at that output rate? 100 c. If the firm Increases output by 1 unit, the firm will make more profit.
