Which of the following statements is always true about the demand functions for good 1 and good 2 if consumer faces prices pi and P2 and has income M? The demand function of good 1 does not depend on M. The demand function of good 2 does not depend on M. The demand level of good 1 is always greater than zero. The demand level for good 2 is always greater than the demand level for good 1. O None of the other statements are true.A consumer can consume three goods, x₁, x2, and x3. In the markets where she buys them, she is a price-taker and faces prices for the three goods equal to P₁, P₂, and p3, respectively. The consumer has m dollars to spend. Her preferences can be represented by the following utility function: U(x₁, x₂, x3) = x₁x²x². X a) Derive the consumption bundle that maximizes the consumer's utility, subject to her budget constraint. b) Show that the optimal consumption bundle found in part a) is a global maximum.

Her preferences over these two goods can be represented by the utility function U(x,y) =x + 3y^1/2 where x represents the number of pounds of coffee and y represents the number of cups of tea. a) Given her preferences, find her demand functions for coffee (x) and tea (y). b) Suppose that the price of a pound of coffee is $4 and that she has $56 to spend on coffee and tea. Write her demand curve for tea. Illustrate her demand curve. c) Suppose that the price of a cup of tea is $1 (the price of coffee and income remain $4 and $56, resp.).
