Accounting Error
1. The problem appears to involve evaluating a financial ledger or balance sheet with numerous values for assets, liabilities, and owner's equity.
2. The key concept in such accounting problems is that the accounting equation must hold: $$\text{Assets} = \text{Liabilities} + \text{Owner's Equity}$$.
3. From the data, assets are listed as cash $90,000$ and supplies $15,000$, summing to total assets:
$$90,000 + 15,000 = 105,000$$
4. On the liabilities side, notes payable is $30,000$. There are other numbers but unclear if they are liabilities or capital.
5. On owner's equity, capital amounts are given like $20,500$, $40,000$, $100,000$ etc., but it's unclear how to sum these correctly without clear labels.
6. Your mistake likely is mixing different repetitions of values without clear distinction between asset, liability, and equity categories.
7. To fix this, clearly separate and sum all asset accounts, sum all liability accounts, and sum all owner's equity accounts, then verify the equation:
$$\text{Assets} = \text{Liabilities} + \text{Owner's Equity}$$
This ensures the ledger balances correctly.
Final answer: Without clear, non-repeated sums for each category, the accounting equation will not balance. Organize data properly by category and sum consistently.
