Final answer:
The owner's equity in the property is $310,000.
Step-by-step explanation:
Equity is the value of an asset minus any liabilities or debts against it. In this case, the value of the property is $320,000 and there are loans of $10,000 against it. To calculate the owner's equity, we subtract the loans from the property value: $320,000 - $10,000 = $310,000.
Therefore, the owner's equity is $310,000 (option b).
