Answer:
$15,000
Explanation:
Given that,
Credit balance in Unearned Revenue account = $10,000
Advance payment by a customer = $12,000
Revenue earned during January = $7,000
Balance in unearned revenue:
= Credit balance in Unearned Revenue account + Advance payment by a customer - Revenue earned during January
= $10,000 + $12,000 - $7,000
= $15,000
Therefore, the balance in Unearned Revenue on January 31, 2019 is $15,000.
