Answer:
$8,000
Step-by-step explanation:
From the question above it is showed that the total prepaid rent paid by Vernon for the six months period (November-April) was $24,000 (6 × $4,000).
The amount to be deducted for rent expense for the year 2018 will be $8,000 (2months × $4,000).
This rent expense will be deducted for 2018 tax purposes only because it was incurred in 2018.
