Airporter Price Fixing? Hustle and Speedy provide transportation service from downtown to the city airport. Assume that low-price guarantees are illegal. The average cost per passenger is constant at $10. Here are the possible outcomes:

• Price fixing (cartel). Each firm has 15 passengers at a price of $25.

• Duopoly (no price fixing). Each firm has 20 passengers at a price of $20.

• Underpricing (one firm charges $20 and the other charges $25). The low-price firm has 28 passengers and the high-price firm has 5 passengers. Hustle chooses a price first, followed by Speedy. Draw a game tree for the price-fixing game and predict the outcome.
