9.(3.5 points) Changes in all of E's balance sheet accounts during the current year, EXCEPT the change in Es retained earnings account, follow. Compute E's net income (or net loss) for the year assuming the only two entries E made to her retained earnings account during the year were for a cash dividend declared and paid of $30,000 and for her net income (or net loss) for the year. This is NOT a statement of cash flows problem - do NOT format it like a statement of cash flows problem; it is similar to E4.1 in your text. Cash increased $50,000 Fixed assets decreased $75,000 Accumulated depreciation increased $10,000 Accounts payable increased $20,000 Unearned revenue decreased $ 5,000 Common stock increased $10,000 Additional paid-in-capital increased $90,000
