In an economy, the desired consumption and investment functions are given by ch = 2,000+ 0.907 4,000 = 1,000 - 4,000 where Y is output and is the real interest rate Government purchases are G = 2,100 The equation for desired national saving in: s=-4,100+ 0.10Y+4.000 Using the condition that at equilibrium quantity of goods supplied a quantity of goods demanded, determine the real interest rates that clear the goods market when Y = 10,000 and Y - 12,000, When Y = 10,000, the equilibrium rate of interest is; (Enter your response as a percentage rounded to the nearest Integer)
