Sarah rents a car to take her to the airport in the morning and return her home that evening. Halfway to the airport, she picks up a friend who accompanies her to the airport. That night, she and her friend return to Sarah's home. The total cost is $20.00. If the amount to be paid is to be split fairly, how much money should Shirley pay?

That depends upon how Shirley gets home and how much of the $20 was airport parking. This is not a math problem, it is more an etiquette question. Shirley should offer to pay half. She is getting escort service, after all.

Who is Shirley?
