Suppose that the demand and supply functions for good x are given as follows: O. =120 -2P, + / + P. and Of = =30 + P, -21 + s-2f where P. denotes the price of good x, P, denotes the price of a related product y, I denotes income, I denotes tax firms face, s denotes subsidy and f denotes factor prices. What happens to the price and quantity equilibrium of good x as factor prices (f) rises? O Price equilibrium falls while quantity equilibrium rises. O Price equilibrium rises while quantity equilibrium falls. Both equilibrium price and quantity fall. O Both equilibrium price and quantity rise
