David went from Philadelphia to Miami to attend a 3 day business conference related to his work. He also spent time sightseeing. He was absent for 9 days total, the days spent as follows:

Saturday - Tuesday: Sightseeing

Wednesday - Friday: Business

Saturday - Sunday: Sightseeing

David, who owns his business, pays the following expenses: Airplane ticket: 1,800 Lodging: [150/night x 8 nights](Saturday to following Saturday) Meals [120 day/9 days]

David's Deductible Expenses are:

A. -0-

B. 630

C. 2,430

D. 1,230

E. 810

When trying this problem on my own, I got 670. I only counted 3/9 days were business, so the airplane ticket wasn't deductible. Then, I only deducted for three nights of lodging and 50% of 3 days of meals. I remember learning that travel days can be considered business days, so should the travel days be 5/9 insteaD and what would the answer be?
