Final answer:
To find Marvin Services Corporation's retained earnings, we calculate total assets and subtract total liabilities and common stock from them. The calculation shows that the retained earnings for the corporation is $33,000.
Step-by-step explanation:
To determine the balance of Marvin Services Corporation’s retained earnings, we must apply the accounting equation which states that Assets = Liabilities + Shareholders' Equity. Since retained earnings is a part of shareholders' equity, we can rearrange this equation to solve for retained earnings: Retained Earnings = Assets - Liabilities - Common Stock.
The total assets are calculated as the sum of cash, accounts receivable, supplies, prepaid insurance, and equipment, which equals $7,000 + $8,000 + $2,000 + $4,000 + $44,000 = $65,000.
Total liabilities are the sum of accounts payable, notes payable, and unearned service revenue, totaling $6,000 + $8,000 + $3,000 = $17,000.
Subtracting the total liabilities and common stock from total assets gives us the retained earnings: $65,000 - $17,000 - $15,000 = $33,000.
