Answer:
Stockholders' equity at the end of the year was $110,000.
Explanation:
Beginning Balance of Stockholder's Equity = $40,000
Net Income for the year = $90,000
Dividend declared in the year = $20,000
Ending Balance of Stockholder's Equity = Beginning Balance of Stockholder's Equity + Net Income for the year -Dividend declared in the year
Ending Balance of Stockholder's Equity = $40,000 + $90,000 - $20,000
Ending Balance of Stockholder's Equity = $110,000
