Rui's utility function is U = X + 25X7 +7 Let the price of good X be px, the price of good Z be normalized to $1.00, and U be her level of well-being. What is her expenditure function ? Rui's expenditure function (E) is (Property format your expression using the tools in the palette. Hover over tools to see keyboard shortcuts. E. Derive her uncompensated demand curve for X. Let Y be her income. Rui's uncompensated demand curve for good X is X = .(Properly format your expression using the tools in the palette.) Derive her compensated demand curve for X Rui's compensated demand curve for good X is X = .(Properly format your expression using the tools in the palette.)Styles 7 To find the expenditure function, substitute the optimal values for good X and good Z into E = PxX+Z The optimal values are: H ( PX - 1 ) ( U + 0.04) X = 5 - 0.04. Px (U +0.04) Z= - 0.04. 5 Display Settings W P
