Final answer:
A commercial bank receiving a new demand deposit of $100 would be able to extend new loans in the amount of $90.
Step-by-step explanation:
A commercial bank receiving a new demand deposit of $100 would be able to extend new loans in the amount of $90.
According to the given information, the bank is subject to a 10 percent reserve requirement.
This means that the bank must hold 10 percent of its demand deposits in reserves.
Since the new deposit is $100, the bank must hold $10 (10% of $100) in reserves and can use the remaining $90 to extend new loans.
