Suppose that currency in circulation (C) is $100 billion, the amount of checkable deposits (D) is $750 billion, and excess reserves (ER) are $15 billion. Also, the required reserves (RR) are $37.5 billion. Calculate the money supply (M), the total reserves (R), the monetary base (MB), the currency-to-deposit ratio (c), the required reserve ratio (rD), the excess reserve-to-deposit ratio (e), and the money multiplier (m).
