Answer:
College earned revenue of $24,000 during 2018
Explanation:
Given:
Opening balance of unearned revenue account = $7,000
Unearned revenue credited to college = $29,000
Closing balance = $12,000
Revenue earned by college during the year = Opening balance + unearned revenue during the year - closing balance
= 7,000 + 29,000 - 12,000
=$24,000
College earned revenue of $24,000 in 2018.
