Suppose that the demand and supply functions for good x are given as follows: Of = 240-2P. + 1 - P, and Of = -30+ P. - 21 + s-2f where Py denotes the price of good x. P, denotes the price of a related product y. I denotes income, t denotes tax firms face, s denotes subsidy and f denotes factor prices. Suppose also that exogenous variables are given as follows: Income (1) = 450, Price of the related product (P ) = 30, tax (t) =24, subsidy (s)-15 and factor prices (f)=36 4.45 1.26 2.13 4.08
