Final answer:
The ending balance in the Deferred Revenue account for Apple Inc. would be $7,000,000 after selling $20.4 million in iTunes gift cards and having $13.4 million redeemed.
Step-by-step explanation:
The student asked about the ending balance in the Deferred Revenue account for Apple Inc. after it sold $20.4 million in iTunes gift cards in November and customers redeemed $13.4 million of the gift cards in December. Deferred revenue, also known as unearned revenue, represents a liability for services or goods which have been sold but not yet delivered or provided.
To calculate the ending balance in the Deferred Revenue account, you subtract the amount redeemed ($13.4 million) from the total amount sold ($20.4 million). Therefore, the ending balance is $20,400,000 (sold) - $13,400,000 (redeemed) = $7,000,000.
