Co i Use the Lagrange technique to maximize utility u = xy + x subject to the budget constraint 6x + 2y = 110. Use Cramer's Rule to find the optimal values of x, y, and 1 . Show the bordered Hessian Matrix and use it to determine if there is a maximum or minimum. d (In(Q)) E) d(In(p)) Q20 Q = P 4 According to Hotelling's Rule, the price of oil can be described Pt = Pt-1ert Pt Pt-1 t t - 1 Pt
