Answer:
Salaries and Wages are owed so they are now liabilities. They are also expenses and will reduce the Net Income.
Rent Revenue was in advance for 2 months meaning one of those months will be December which is in the current period so;
= 7,520/2
= $3,760 will be added to net income for the year
The same amount will be removed from Liabilities as the revenue has now been recognized.
Depreciation reduces the value of Fixed assets so will be deducted from Assets.
It is also an expense so it will reduce Net Income.
Whatever happens to Net Income will happen to Stockholders' equity as well because Net Income is an Equity account.
