Suppose there are only two goods - Food (F) and Shelter (S). The demand equations for these two goods depend on their prices, pF and pS as follows: DF (pF, pS) = 10 - 2pF - pS DS (pF, pS) = 10 - pF - 2pS The supply curves depend only on their own prices: SF (pF) = pF SS (pS) = 5pS Determine the equilibrium price and quantity of these goods
