Final answer:
Given a reserve ratio of 5% and total deposits of $500,000, the First National Bank's required reserves are $25,000. Since it holds actual reserves of $100,000, its excess reserves are calculated to be $75,000.
Step-by-step explanation:
To answer the question regarding First National Bank's excess reserves, we need to use the given reserve ratio and the total deposits. The reserve ratio is 5%, and the total deposits are <$500,000>. Therefore, the required reserves would be 5% of $500,000, which is $25,000. First National Bank actually holds $100,000 in reserves. To find the excess reserves, we subtract the required reserves from the actual reserves:
$100,000 (actual reserves) - $25,000 (required reserves) = $75,000 (excess reserves).
So, the correct answer is (d) $75,000.
