Given that Kip's utility function is U(q1, 92) = 915+ 925 a) (2 points) Calculate the marginal rate of substitution (MRS) of good 1 for good 2 ? b) (8 points) Expenditures are given E = P191 + P292. Minimize expenditures while achieving at least utility U. Derive the compensated demand functions for the two goods q, and 92 using the method of Lagrange. c) (5 points) What is Kip's expenditure function
