"2.6 Continental Airlines Goes Marginal. In the 1960s, Continental Airlines puzzled observers of the airline industry and dismayed its stockholders by running flights with up to half the seats empty. The average cost of running a flight was $4,000, a figure that includes fixed costs such as airport fees and the cost of running the reservation system. A half-full aircraft generated only $3,100 of revenue.
Use the marginal principle to explain why Continental ran half-empty flights.It will be sensible to run a half-empty flight if the marginal of flight is than $.

Del's and Rodney's are two plumbing services in a gentrifying area of South East
London. Within the area they service, the two firms operate as a duopoly and
together serve one hundred percent of the available local market. One of their key
lines of business is visiting customer's homes to install a new shower rail. A student
project has been investigating the local plumbing business and has estimated the
following information for Del's and Rodney's:
Total demand for new shower rails per week is given by
P = 200 - 4Q
Where Q is total market demand and can be divided between Del's (qd) and
Rodney's (qr) such that
Q = qd + qr
Assuming that the marginal cost of serving an extra customer is £40 for each, and
that marginal revenue for Del is given by
MRd
2008qd - 4qr
And marginal revenue for Rodney is given by
MRr
Then
2008qr - 4qd

We had in round numbers 500,000 buyers of cars on the $440 basis, and I figure that on the $360 basis we can increase sales to possibly 800,000 cars for the year - less profit on each car, but more cars, more employment of labor, and in the end we get all the total profit we ought to make." If Ford's estimate as correct, what was the price elasticity of demand for his cars? By how much did total revenue increase? 7 Using the data from question 6, above, write the demand curve equation for Henry Ford's cars. 8 Using the demand curve equation from question 7, build a graphic to sell Ford cars to the public in 1916.arrow_forward6 In 1916, Henry Ford was quoted as saying the following: "There are men who will pay $360 for a car who would not pay $440.
