King Enterprises is a book wholesaler. King hired a new accounting clerk on January 1 of the current year. The new clerk does not understand accrual accounting and recorded the transactions below based on when cash receipts and disbursements changed hands rather than when the transaction occurred. King uses a perpetual inventory system, and its accounting policy calls for inventory purchases to be recorded net of any discounts offered.

Jan. 10 Paid Aztec Enterprises $9,800 for books that it received on December 15. (This purchase was recorded as a debit to Inventory and a credit to Accounts Payable on December 15 of last year, but the accounting clerk ignores that fact.)
Dec. 27 Received books from McSaw Inc. for $20,000; terms 2/10, n/30.
Dec. 30 Sold books to Booksellers Unlimited for $30,000; terms 1/10, n/30. The cost of these books to King was $24,500.
