Final answer:
Expenses for food are not considered reimbursable under an accountable plan if they would have been incurred regardless of the temporary assignment.
Step-by-step explanation:
The amounts incurred by Jerry for food are not considered reimbursable under an accountable plan because Jerry would have had to spend money to eat even had he been at home. In an accountable plan, the employer can reimburse employees for valid business expenses that are necessary for their work. However, expenses that would have been incurred regardless of the temporary assignment, such as food, are not considered reimbursable under this plan.
