2.6 Ryanair and easyJet are the two largest low-cost airlines in Europe. In 2015, the cost per available seat kilometer (CASK) was 3.60¢ (cents) for Ryanair and 6.44¢ for easyJet. Assuming that Ryanair and easyJet compete on a single route, use a graph to show that their equilibrium quantities differ. (Hint: See Q&A 11.1 and Figure 11.4.)
