Explanation / Answer

(a) Option (C)

Total reserves ($ Billion) = Required reserves + Excess reserves

= (Deposits x Required reserves ratio) + Excess reserve = (900 x 20%) + 2 = 180 + 2 = 182

(b) Option (B)

Monetary base ($ Billion) = Currency + Total reserves = 500 + 182 = 682

(c) Option (D)

Money supply ($ Billion) = Currency + Deposits = 500 + 900 = 1,400
