I need to find the business travel expense from the following: Travel includes a trip to a weight-lifting seminar in Miami, FL. The one-day seminar cost $400. Chris took Traynor and Arnold with him. Airfare was $400 for each of them. The seminar started early in the morning, so they flew down the night before and then left the following morning since the seminar ended late in the day. Traynor and Arnold went to Miami Beach for the day. Lodging was $250 per night for two nights and meals were $100 for each of the three of them ($300 total). They also paid $100 for ground transportation from the airport to the hotel hosting the seminar.
