Suppose that Bridget and Erin make their choices across the two goods , (Microsoft's XBox) and 2 (Sony Playstation). Faced with the same price for both, Bridget is indifferent between the XBox and the Playstation. Using this clue, determine optimal x; and x5 for Bridget. Explain your logic. Note: you have not been given a utility function but the budget constraint is the same as usual. Suppose Erin's preferences are given by U (. ) = X1. T2. Are Erin's preferences the same as Bridget's or are they different? If their preferences are the same, explain why. If they are different, determine x; and x; for Erin
