QUESTION 7 A / w Suppose the budget set and income level is given as in Question 1. Suppose that a consumer's utility is given by u(x,y) = (2x 3 + 3y 3 What is utility obtained at the optimal consumption bundle, and what is the interpretation of the marginal rate of substitution at that point? O Roughly 7.3, and if the consumer gives up 3 units of good y, they would need an additional 2 units of good X to maintain this level of utility. O Roughly 7.3, and if the consumer gives up 2 units of good y, they would need an additional 3 units of good x to maintain this level of utility. O Roughly 11, and if the consumer gives up 3 units of good y, they would need an additional 2 units of good X to maintain this level of utility. O Roughly 11, and if the consumer gives up 2 units of good y, they would need an additional 3 units of good x to maintain this level of utility
