a) Draw the demand curve and the associated marginal revenue curves for the two individual sub-markets and the market as a whole on three sets of axes. Indicate all the important points. b) Calculate the number of flights offered and the prices charged in each market segment, as well as the total number of flights that will be offered by the airline if it practices third degree price discrimination.
