Problem 1 Suppose that a person has a utility U = 3x1 + 9x2, where x1 is the quantity of good 1 consumed, and x2 is the quantity of good 2 consumed. Answer the following questions, and write your answers in the Answer Sheet. Find the equation representing the person’s indifference curve for a level of utility represented by the constant K. (Hint: Isolate x1 on one side.) Find the person’s marginal utility with respect to good 1 (MUx1 )....
