The cost in dollars of operating a jet-powered commercial airplane Co is given by the following equation
Co = k*n*v^(3/2)
where
n is the trip length in miles,
v is the velocity in miles per hour, and
k is a constant of proportionality.
It is known that at 590 miles per hour the cost of operation is $300 per mile. The cost of passengers' time in dollars equals $226,000 times the number of hours of travel. The airline company wants to minimize the total cost of a trip which is equal to the cost of operating plus the cost of passengers' time.
At what velocity should the trip be planned to minimize the total cost?
HINT: If you are finding this difficult to solve, arbitrarily choose a number of miles for the trip length, but as you solve it, you should be able to see that the optimal velocity does not depend on the value of n​

Suppose that an airplane basic operating cost is c per a passenger. However, it can price add-ons (better sits, extra beverages, wi-fi) to generate extra fees averaging p̄ from naive type of passangers. A fraction α of customers are naive, and do not foresee these add-ons. The remaining fraction (1 − α) are sophisticated, and can avoid the add-ons at an effort cost of e. For simplicity, assume that the add-ons do not cost anything for the airlines to provide....
