Relevance (LO1, LO2). Sam Walters is leaving tomorrow for a three-day business trip and is trying to decide the most economical way to get to and from the airport and his home. Sam could either drive (using his own car) or take the shuttle. If Sam drives, then he estimates that it will cost $0.30 per mile driven in operating costs (e.g., for gas and oil) and $7.50 per day for parking. The one-way cost of the shuttle is $25. Sam’s home is exactly 30 miles from the airport.

Required:

What are the relevant costs for each of Sam’s two options?
