Final answer:
The total stockholders' equity reported in the company's balance sheet dated December 31, current year, is $396,000.
Step-by-step explanation:
To determine the total stockholders' equity reported in the company's balance sheet dated December 31, current year, we need to take into account the changes in capital stock, net income, dividends, and the beginning and ending balance of retained earnings.
The formula to calculate the total stockholders' equity is: Beginning Capital Stock + Net Income - Dividends + Ending Retained Earnings.
In this case, the beginning capital stock is $180,000, the net income is $108,000, the dividends are $12,000, and the ending retained earnings balance is $120,000. So, the total stockholders' equity is $180,000 + $108,000 - $12,000 + $120,000 = $396,000.
