Final answer:
The monthly fee a student pays to park at school is relevant when deciding whether to take a train or drive for a weekend trip to visit an out-of-town friend.
Step-by-step explanation:
The monthly fee a student pays to park at school is relevant when deciding whether to take a train or drive for a weekend trip to visit an out-of-town friend. This fee should be taken into consideration as part of the overall cost of driving. For example, if the monthly fee is $50 and the trip will take place over two weekends, the total cost of parking for the trip would be $100. However, if the train ticket is cheaper than the cost of parking, then taking the train would be a more cost-effective option.
