Answer: $18,000

Explanation:

Given that,

Began 2018 with a Normal balance = $5,000

Ended 2018 with a normal balance = $11,000

Unearned Revenue account was credited = $24,000

Revenue earned by professor in 2018:

= Beginning unearned revenue + Advance payments - Ending unearned revenue

= $5,000 + $24,000 - $11,000

= $18,000

Therefore, $18,000 revenue earned by professor in 2018.
