Scenario 10.1
Use the following to answer the questions.
Megabus is a bus line operating in the Northeast and Midwestern United States, plus in Canada. It offers travelers a cheap alternative to driving and flying between large cities, keeping the fares extremely low yet offering the latest technology. Unlike the traditional Greyhound bus line, Megabus is an express service, and is equipped with Wi-Fi, video screens, headsets, and seat belts. Many buses also run on biodiesel fuel. Additionally, Megabus picks up and drops off people in the centers of cities rather than at inconveniently-located terminals. Patrons can book tickets at Megabus.com, where some fares begin at just $1. Routes are limited, and are offered out of cities such as Toronto, New York, Baltimore, Philadelphia, and Chicago. Recently, its competitor Greyhound has launched two new bus lines, BoltBus and NeOn, with similar fares and high-tech amenities. A fare on a NeOn bus from Buffalo, New York, to New York City is $50.00 round trip, while the same fare through Greyhound's traditional bus line costs $92.00. The benefit of Greyhound's traditional line is that there are more departure times and more stops in smaller towns along the way.
