Final answer:

Step-by-step explanation:
The student is asking to complete the balance sheet for First Main Street Bank, given that the economy's money supply equals checkable deposits of $800,000 and the required reserve ratio (r) is 25%. With no excess reserves and no cash leakage, the bank must hold 25% of the checkable deposits as reserves, which amounts to $200,000. This $200,000 will be the bank's required reserves, and the remaining $600,000 (75% of $800,000) is available to be given out as loans.
