Answer:
Assets of $170 billion.
Explanation:
Net worth of a bank is calculated by deducting total Liabilities from total assets value. It is the net asset value of the bank. Deposits are not being considered because they have already been added in the liabilities value.
Net worth of the bank = Total Assets - Total Liabilities
$20 billion = Total Asset - $150 billion
Total Asset = $20 billion + $150 billion
Total Asset = $170 billion
