Based on your answers to the WipeOut Ski Company in Exercise 7.3, now imagine a situation where the firm produces a quantity of 5 units that it sells for a price of 25 each. What will be the companys profits or losses? How can you tell at a glance whether the company is making or losing money at this price by looking at average cost? At the given quantity and price, is the marginal unit produced adding to profits?
HighFlyer Airlines wants to build new airplanes with greatly increased cabin space. This will allow HighFlyer Airlines to give passengers more comfort and sell more tickets at a higher price. However, redesigning the cabin means rethinking many other elements of the airplane as well, like engine and luggage placement, and the most efficient shape of the plane for moving through the air. HighFlyer Airlines has developed a list of possible methods to increase cabin space, along with estimates of how these approaches would affect the planes operating costs and ticket sales. Based on these estimates, Table 13.5 shows the value of R, how much should the firm invest in R on top of the private return; that is, an R private return to HighFlyer Airlines would have a 9 social return. How much investment is socially optimal at the 6 interest rate?
If the transit system were regulated to provide the most allocatively efficient quantity of output, what output would it supply and what price would it charge? What subsidy would be IIECESSEIIY to insure this efficient provision of transit services?
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.
A firms marginal cost curve above the average variable cost curve is equal to the films individual supply curve. This means that every time a firm receives a price from the market it will be willing to supply the amount of output where the price equals marginal cost. What happens to the films individual supply curve if marginal costs increase?
Urban transit systems, especially those with rail systems, typically experience significant economies of scale in operation. Consider the transit system data in Table 11.4. Note that the quantity is in millions of riders.
Crawford Computing finds that its weekly profit, in dollars, from its production and sale of x laptop computers is P(x)=-.002x^3-.15x^2+400x-800 Currently, Crawford builds and sells 9 laptops weekly. (a) what is the current weekly profit? (b) how much profit would be lost if production and sales dropped to 8 laptops weekly? (c) what is the marginal profit with x=9? (d) use answers from parts (a) and (c) to estimate the profit resulting from the production and sale of 10 laptops weekly.
ADJ Enterprises produces hydrothermocorticoids. The table below shows the costs of producing various quantities of hydrothermocorticoids.

Show your calculations. Explain how and why your answers will change or…
Why Marginal Cost (MC) is 1?? I did my calcutation and is 2. I replace on fucntion Q = L + (5)2 = L + 25, so L = Q - 25 and put on TC = 2(Q - 25) + 20(5) So TC = 2Q - 50 + 100 = 2Q + 50, then MC = dTC / dQ = 2 You may be replaced TC = wL + rK, but this function no contains Q variable Please confirm that. Thanks
