Suppose the Reserve-Deposit Ratio Is

Suppose the reserve-deposit ratio is
res = 0.5 - 2 i,
where i is the nominal interest rate.The currency-deposit ratio is 0.2 and the monetary base equals 100.The real quantity of money demanded is given by the money demand function
L(Y,i)= 0.5Y - 10 i,
where Y is real output.Currently the real interest rate is 5% and the economy expects an inflation rate of 5%.Assume the price level P is equal to 1.
(a)Calculate the money multiplier.
(b)Calculate the reserve-deposit ratio.
(c)Calculate the money supply.
(d)Calculate the value of output Y that clears the asset market.
