Suppose that the inverse demand function (where the demand curve is rearranged so that price is a function of quantity) for movies is p = 120 - Q1 for college students and p = 120 - 2Q2 for other town residents. What is the town's total demand function (Q = Q1 + Q2 as a function of p)? Use a diagram to illustrate your answer. (By looking at your diagram, you'll see that the total demand function has a kink, so care must be used in writing the total demand function.)
