Suppose the Central Bank Purchases $10,000 of Treasury Bonds from You

Suppose the Central Bank purchases $10,000 of Treasury bonds from you and that you deposit the $10,000 into your checking account deposit at Bank Y. Assume that Bank Y has no excess reserves at the time you make your deposit and that the required reserve ratio is 20 percent.
a. Use a T-account to show the initial effect of this transaction on Bank Y's balance sheet.
b. Suppose that Bank Y makes the maximum loan they can from the funds you deposited. Use a T-account to show the initial effect on Bank Y's balance sheet from granting the loan. Also include in this T-account the transaction from question (a).
c. Now suppose that whoever took out the loan in question (b) writes a check for this amount and that the person receiving the check deposits it in Bank Z. Show the effect of these transactions on the balance sheet of Bank Y and Bank Z, after the check has been cleared. On the T-account for Bank Y, include the transactions from questions (a) and (b).
d. What is the maximum increase in checking account deposits that can result from your $10,000 deposit? What is the maximum increase in the money supply? Explain
