Final answer:
To set up the T-account balance sheet for the bank and calculate its net worth, list the assets, liabilities, and subtract the liabilities from the assets.
Step-by-step explanation:
In order to set up the T-account balance sheet for the bank, you need to list the assets and liabilities.
The bank's assets include reserves of $50, government bonds worth $70, and loans of $500.
The bank's liabilities include deposits of $400.
To calculate the bank's net worth, you subtract the liabilities from the assets. In this case, the bank's net worth is $220.
