A consumer is choosing consumption , and r2 to maximise a utility function u(21, 12) = ]r, subject to ($1, 12) ER? and a budget constraint pic1 + p212 = m for some prices p1 > 0, p2 > 0 and income m >0. (a) Write down the Kuhn-Tucker conditions for this problem. (b) Argue that neither I1 = 0 nor 12 = 0 is possible at a global maximiser (21, x2) for the problem. (c) Find a global maximiser
