Question 3 Three firms sell related products in a market. Their supply functions are: 97 = P1 8 = 2 P2 = 2 P3 The firms face the following demands: 41 = 3 - 5 P1 + 3 P2 + 6 P3 d 92 = -43 + 3 P1 - 2 P2 + 5 P3 d 93 = -92 + 6 P1 + 6 P2 - 3 P3 Given the above supply and demand functions, what price must firm 1 charge to equate supply and demand for all the firms? Note that you do not need to solve for all equilibrium prices. P = Number
