The Correct Answer and Explanation is:
To solve Equation 7 and calculate the owner’s equity at year end, we will apply the expanded accounting equation: Assets=Liabilities+Owner’s Capital+Revenues−Expenses−Withdrawals\text{Assets} = \text{Liabilities} + \text{Owner’s Capital} + \text{Revenues} – \text{Expenses} – \text{Withdrawals}
Given Values in Row 7:
- Liabilities = 1,988
- Owner’s Capital = 41,194
- Withdrawals = 6,196
- Revenue = 52,210
- Expenses = 42,597
- Assets = Missing
- Owner’s Equity (year end) = To be calculated
Step 1: Calculate Ending Owner’s Equity
Using: Owner’s Equity=Owner’s Capital+Revenue−Expenses−Withdrawals\text{Owner’s Equity} = \text{Owner’s Capital} + \text{Revenue} – \text{Expenses} – \text{Withdrawals}
Substitute values: Owner’s Equity=41,194+52,210−42,597−6,196\text{Owner’s Equity} = 41,194 + 52,210 – 42,597 – 6,196 =93,404−48,793=44,611= 93,404 – 48,793 = \boxed{44,611}
Step 2: Calculate Assets (if needed)
Now use: Assets=Liabilities+Owner’s Equity\text{Assets} = \text{Liabilities} + \text{Owner’s Equity} Assets=1,988+44,611=46,599\text{Assets} = 1,988 + 44,611 = \boxed{46,599}
✅ Final Answer for Equation 7:
Owner’s Equity at year end = $44,611
Explanation
In accounting, the expanded accounting equation incorporates both permanent and temporary components of owner’s equity. This includes capital contributed by the owner, revenues earned, expenses incurred, and withdrawals taken during the accounting period.
To find the owner’s equity at year-end for Equation 7, we use the formula: Ending Owner’s Equity=Owner’s Capital+Revenues−Expenses−Withdrawals\text{Ending Owner’s Equity} = \text{Owner’s Capital} + \text{Revenues} – \text{Expenses} – \text{Withdrawals}
This formula reflects the net change in owner’s equity due to business activities. In this case, the owner originally invested $41,194. The business earned revenue of $52,210, which increases equity. However, the business also had $42,597 in expenses and the owner withdrew $6,196, both of which decrease equity. After accounting for these factors, the ending owner’s equity totals $44,611.
This figure represents the residual interest in the company’s assets after deducting liabilities. If needed, we can calculate the total assets using the formula: Assets=Liabilities+Owner’s Equity\text{Assets} = \text{Liabilities} + \text{Owner’s Equity}
Which yields $46,599. This confirms that the business’s financial position remains solvent, as assets exceed liabilities. Understanding how these elements interact is essential for tracking a company’s financial performance and position throughout the year.
