pts Assume that the money demand function is (M / p)d = 2,200 - 200r, where r is the interest rate in percent. The money supply M is 2,800, and the price level P is 2. If the price level is fixed and the supply of money is raised to 3,200, then the equilibrium interest rate will: O drop by 7.5 percent. O drop by 1 percent. drop by 7 percent. drop by 0.5 percent.
