M. and prices p1 and 3):; using; the MRS and the budget line. (1)} Suppose M = 60. pl 2 2 and p2 = 1 but then p1 falls to 1. For good 1 compute the substitution and income effects of this price change. and show these effects on a clear complete graph. (c) Does the substitution effect have to he positive for any CobbDouglas utility function? Explain
