Kuanysh's preferences over two goods are given by utility function u(x1, x2) = xx2, and the prices of good 1 and good 2 are given by p and p2. In the remaining questions, Kuanysh is endowed with w = 90 units of good 1 and w = 30 units of good 2 (and has no income). 15. Consider price ratios 1 equal to 10,, *, 5 and 100.
