Q3 Blue Jet Airlines has an evening flight from Kansas City to Chicago with an average of 80 passengers and a return flight the next afternoon with an average of 50 passengers. The plane makes no other trip. The charge for the plane remaining in Chicago overnight is $1,200 and would be zero in Kansas City. The airline is contemplating eliminating the night flight out of Kansas City and replacing it with a morning flight. The estimated number of passengers is 70 in the morning flight and 50 in the return afternoon flight. The one-way ticket for any flight is $200.

(See the table)
Kenen, 2000)
a)
Labour (L) is the fixed input and Capital (K) is a variable input.
b)
Labour cost per hour = $20
Total labour hours = 20
Total fixed costs of firm = $20*20 = $400
c)
Cost per hour of capital = $80
Variable cost of 475 = 6*$80 = $480
d)
Variable units to maximise profit = 5 units of capital
e)
Sale units =450
