Suppose that the demand and supply functions for good x are given as follows: Q-120-2P, +1+P, and Q=-30+P-21+3-2f where P, 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, txx (1)-24, subsidy (s)-15 and factor prices (1)-36. What is the cross price elasticity of demand at the equilibrium? -0.27 and thus products x and y are complements. 0.27 and thus products x and y are substitutes. -0.23 and thus products x and y are complements. 0.23 and thus products x and y are substitutes.

Question
Suppose that the demand and supply functions for good x are given as follows: Q-120-2P, +1+P,
and Q=-30+P, -2r+s-2/ where P, 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 (I)-450, Price of the related product
(P₂)-30, tax (1)-24, subsidy (s)-15 and factor prices (1)-36.
What is the cross price elasticity of demand at the equilibrium?
-0.27 and thus products x and y are complements.
0.27 and thus products x and y are substitutes.
-0.23 and thus products x and y are complements.
0.23 and thus products x and y are substitutes.
