Answer:
The amount of the expenses that Tom may deduct as a charitable donation on his Schedule A is $400.
Step-by-step explanation:
Since Tom's weekend trips were devoid of any significant element of personal pleasure and assuming that he can fully itemize and deduct all expenses incurred, the total amount of the expenses incurred in relation to the trips may be deducted by Tom as a charitable donation.
Therefore, we have:
Amount deductible as a charitable donation = Special uniform worn while performing services + Meals and lodging while on weekend trips = $100 + $300 = $400
Therefore, the amount of the expenses that Tom may deduct as a charitable donation on his Schedule A is $400.
