8. The demand and supply functions for two interdependent commodities are given by QD, = 100 – 2P, + P, 5+ 2P, — ЗР, - Os, = -10 + P, Os, = -5 + 6P, where Qp, Qs,and P, denote the quantity demanded, quantity supplied and price of good i, respectively. Determine the equilibrium price and quantity for this two-commodity model. 8.
