Final answer:
The bank's net worth is calculated by subtracting its total liabilities from its total assets. In this case, the assets are $620, and the liabilities are $400, resulting in a net worth of $220.
Step-by-step explanation:
Calculating the Bank's Net Worth
To calculate the net worth of the bank, we need to consider the bank's assets and liabilities. Let's create a T-account balance sheet for the bank:
Assets
- Reserves: $50
- Government Bonds: $70
- Loans: $500
Liabilities
The total assets of the bank are calculated by adding reserves, government bonds, and loans, which give us $50 + $70 + $500 = $620. The total liabilities are the total deposits, which is $400.
The net worth of a bank is the difference between its total assets and total liabilities. In this case, the net worth is calculated as $620 - $400 = $220. Therefore, the bank's net worth is $220.
