3. Suppose that the market for tea is described by the demand and supply functions Dt = 1005pt + 3pc St= -10 + 2pt And the market for coffee by Dc = 1208pc + 2pt Sc= 10 + 5pc Where pt is the price of tea, pc is the price of coffee, D, and Stare the quantities of tea demanded and supplied respectively, and De and Scare the quantities of coffee demanded and supplied. Express the system of equations that describes the markets for tea and coffee into the form Ap-b. Solve for the equilibrium prices of tea and coffee.
