Answer:
The correct answer is $30,000.
Step-by-step explanation:
According to the scenario, the given data are as follows:
Own investment = $20,000
Debt from bank = $10,000
As the business is sole proprietor, there is unlimited liability of the loss whether it is own investment or borrowed from a bank.
So, the total loss can be calculated as:
Total loss = Own investment + Debt from bank
= $20,000 + $10,000
= $30,000
Hence, the total loss is $30,000.
