Company data suggest that the total cost of a certain flight is approximately C(x) = 120x – 0.38x + 0.0005x, where x is the number of passengers. a. Determine the marginal cost function. b. Estimate the marginal cost of an additional passenger if the flight already has 150 passengers. c. Is it more expensive to add another passenger when x = 150 or when x = 200?
