Draw her budget constraint. b.Suppose also that her utility function is given by the equaion U(M,P) = 2M + P. What combination of meat and potatoes should she buy to maximize her utility? (Hint:Meat and potaoes are perfect substitutes.) c.Connie's supermarket has a special promotion. If she buys 20 pounds of potatoes (at $2 per pound), she gets the next 10 pounds for free. This offer applies only to the first 20 pounds she buys. All potatoes in excess of the first 20 pounds (excluding bonus potatoes) are still $2 per pound. Draw her budget constraint. d.An outbreak of potato rot raises the price of potatoes to $4 per pound. The supermarket ends its promotion. What does her budget constraint look like now? What combination of meat and potatoes maximizes her utility? (20%) 五、Maurice has the following utility function: U(X,Y) = 20X + 80Y - X^2 - 2Y^2 where X is his consumption of CDs with a price of $ and Y is his consumption of movie videos, with a rental price of $2. He plans to spend $41 on both forms of entertainment. Determine the number of CDs and video rentals that will maximize Maurice's utility. (20%) Happy New Year! and Good luck! --
