Final answer:
The required reserves for the bank with $120 million in deposits and a reserve requirement of 0.15 are $18 million.
Step-by-step explanation:
The required reserves can be calculated by multiplying the deposit amount by the reserve requirement ratio. In this case, the reserve requirement is 0.15 (or 15%). So, the required reserves can be calculated as:
Required Reserves = Deposit amount x Reserve Requirement Ratio
Required Reserves = $120 million x 0.15
Required Reserves = $18 million
Therefore, the bank is required to hold $18 million in reserves.
