Please solve the following

Consider a money market in which money demand is described by the following equation: 4' M+=100+Y50i. P Assume that the equilibrium level of income is 1' =100 , the price level is P =1 , and the current level money supply is M ' = 100. 0 Calculate and describe graphically the money market equilibrium. 0 Suppose the economy is hit by a adverse real shock that reduces income to Y = 80. Illustrate (both numerically and graphically) the effect of the shock on the money market equilibrium. - Illustrate (both numerically and graphically) the central bank response to the shock, if its objective is to keep money supply constant over time. - Illustrate (both numerically and graphically) the central bank response to the shock, if its objective is to keep the interest rate constant over time.
