What two lines on a cost curve diagram intersect at the shutdown point?
A computer company produces affordable, easy-to-use home computer systems and has fixed costs of 250. The marginal cost of producing computers is 700 for the first computer, 250 for the second, 300 for the third, 350 for the fourth, 430 for the fifth, 450 for the sixth, and 500 for the seventh. Create a table that shows the companys output, total cost, marginal cost, average cost, variable cost, and average variable cost. At what price is the zero-profit point? At what price is the shutdown point? If the company sells the computers for 500, is it making a profit or a loss? How big is the profit or loss? Sketch a graph with AC, MC, and AVG curves to illustrate your answer and show the profit or loss. If the firm sells the computers for 300, is it making a profit or a loss? How big is the profit or loss? Sketch a graph with AC, MC, and AVG curves to illustrate your answer and show the profit or loss.

5. Profit maximization and shutting down in the short run Suppose that the market for wind chimes is a competitive market. The following graph shows the daily cost curves of a firm operating in this market. IMG 1 For each price in the following table, calculate the firm's optimal quantity of units to produce, and determine the profit or loss if it produces at that quantity, using the data from the graph to identify its total variable cost. Assume that if the firm is indifferent between producing and shutting down, it will produce. (Hint: You can select the purple points [diamond symbols] on the graph to see precise information on average variable cost.) *Points on the purple line are (1, 14) (4, 10.5) (6, 10) (8, 10.5) (12, 16) (15, 24) (18, 34) IMG 2 If the firm shuts down, it must incur its fixed costs (FC) in the short run. In this case, the firm's fixed cost is $44,000 per day. In other words, if it shuts down, the firm would suffer losses of $44,000 per day until…
The Trouser Company has fixed costs of 2,000 per week. In addition, we have some information about its marginal costs (MC) and total variable costs (TVC) Output 0 30 60 90 100 120 150 MC 140 59 32 59 80 140 275 TVC 0 2850 4080 5310 6000 8160 14,250 Sketch a diagram showing the marginal cost curve, the average variable cost curve, and the firm’s short run supply curve.
Describe how we can identify a competitive firm’s short-run supply curve.
“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.
(The Short-Run Firm Supply Curve) Use the following datato answer the questions below: a. Calculate the marginal cost and average variable costfor each level of production.b. How much would the firm produce if it could sell itsproduct for $5? For $7? For $10?c. Explain your answers.d. Assuming that its fixed cost is $3, calculate the firm’sprofit at each of the production levels determined inpart (b).
10. Problems and Applications Q10 An industry currently has 100 firms, each of which has fixed costs of $16 and average variable costs as follows: Complete the following table by deriving the total cost, marginal cost, and average total cost for each quantity from 1 to 6. Quantity Average Variable Cost Total Cost Marginal Cost Average Total Cost (Dollars) (Dollars) (Dollars) (Dollars) 0 16 1 1 2 2 3 3 4 4 5 5 6 6 The equilibrium price is currently $10. Each firm produces __________ units, so the total quantity supplied in the market is _________ units. In the long run, firms can enter and exit the market, and all entrants have the same costs as in the previous table. As this market makes the transition to its long-run equilibrium, the price will _______ , quantity demanded will ________ , and the quantity supplied by…
Consider the perfectly competitive market for steel. Assume that, regardless of how many firms are in the industry, every firm in the industry is identical and faces the marginal cost (MCMC), average total cost (ATCATC), and average variable cost (AVCAVC) curves shown on the following graph. The following diagram shows the market demand for steel. Use the orange points (square symbol) to plot the short-run industry supply curve when there are 10 firms in the market. (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.) Next, use the purple points (diamond symbol) to plot the short-run industry supply curve when there are 15 firms. Finally, use the green points (triangle symbol) to plot the short-run industry supply curve when there are 20 firms. If there were 20 firms in this market, the short-run equilibrium price of steel would be per ton. At that price, firms in this…
