I need answers to questions d, e and f

Extracted text: 1. Think about a utility function U(x,y) =xy, the budget constraint is px*x +py*y= m. a. Please derive the Marshallian demand functions. b. Please derive the indirect utility function. c. Please derive the expenditure function. If originally m = 8, px=1, py=4. d. What is his optimal consumption? e. What is his maximum utility level? Now px has increased to 2. f. Based on (c), after the price change, how much should be compensated to maintain his original utility level? g. Use the Shaphard's Lemma to derive the Hicksian demand functions. h. Based on (g), after the price change and the compensation, what is his optimal consumption? i. If there is no compensation, after the price change, what is his optimal consumption? j. What is the total effect, substitution effect and income effect? (you can just use good x to show how the effects work)
