Hint: Item b requires two adjustments. 3. Prepare journal entries to record the adjustments entered on the six-column table. Assume Bug-Offs adjusted balance for Merchandise Inventory matches the year-end physical count. 4a. Prepare a single-step income statement for 2021. 4b. Prepare the statement of retained earnings (cash dividends during 2021 were $12,000), for 2021. 4c. Prepare a classified balance sheet for December 31, 2021.
