_ 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 0U BU (8) Find expressions for the marginal utilities, and &y (b) Find the values of these marginal utilities if the current consumption of X is 500 units and the current consumption of Y is 200 units. (0) For the greatest increase in utility, should the individual increase their consumption of X or Y? (Use integers or decimals for any numbers in the expression.) 5U a = D (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? I Uy = D (Round to two decimal places as needed.) 1 (c) For the greatest increase in utility. the individual should increase consumption of E
