Throughout this problem set, let X = R1, and suppose a consumer faces a price vector p = (p1, p2) and has an income m, where 121,122, m > 0. In different questions, we will make different assumptions about what the consumer's utility It : X > R looks like. Throughout, let 1:\" E R1 be the consumer's chosen bundle. 1. Suppose u is increasing. (a) If 3:; = 0, what is 1"\"? (b) If 1:; = 0, what is 1\"\
