Answer:
Allowable Business Expense is $50
Step-by-step explanation:
The entertainment expenses that were paid before the business deal are allowed business expenses and those entertainment expenses that were incurred after the business deal are disallowed business expenses.
So here, the entertainment expense that includes meal which is worth $100 and is the only allowable business expense here that was incurred before the business deal.
The meal with clients are 50% deductible which means only 50% of the $100 is allowed as business expense.
Allowable Business Expense = $100 * 50% = $50
