An individual's utility function for the consumption of x units of good X and y units of good Y is given by U = 100x0'73y0'27 6U 0U (8) Find expressions for the marginal utilities, and 0X 69y (b) Find the values of these marginal utilities if the current consumption of X is 600 units and the current consumption on is 100 units. (6) For the greatest increase in utility, should the individual increase their consumption of X or Y? M 0U (a) a = (Use integers or decimals for any numbers in the expression.) 6U ay (Use integers or decimals for any numbers in the expression.) (b) What is the marginal utility of X at the current levels of consumption? Ux = D (Round to two decimal places as needed.) What is the marginal utility of Y at the current levels of consumption? Uy = 1:] (Round to two decimal places as needed.) i i (c) For the greatest increase in utility, the individual should increase consumption of
