Answer: Debit Unearned fees $6,120, Credit Fees income $6,120.
Explanation: Garcia Publishing received $24,480 from Otisco on April 1 and this was recorded as unearned fees. This means Garcia would have debited cash with $24,480 and credited unearned fees $24,480. Remember the fees was paid at the beginning of April and is for 36-month subscriptions. So, the amount in unearned fees would be unwound to income (fees) over the tenor of the subscription (36 months). Therefore, monthly amortization would be $24,480 divided by 36 months = $680. April 1 to December 31 is 9 months, $680 multiplied by 9 months is $6,120.
