Final answer:
Arthur's allowable business expense deduction for 2022 would be $2,613.
Step-by-step explanation:
In order to determine Arthur's allowable business expense deduction for 2022, we need to consider the specific rules set by the Internal Revenue Service (IRS).
For entertainment expenses, the IRS allows a deduction of 50% of the total amount. Therefore, Arthur's allowable business expense deduction for entertainment would be $2,330 * 50% = $1,165.
For meals provided by a restaurant, the IRS allows a deduction of 100% of the total amount. Hence, Arthur's allowable business expense deduction for meals would be $1,448 * 100% = $1,448.
Therefore, Arthur's total allowable business expense deduction for 2022 would be $1,165 + $1,448 = $2,613.
