o Marginal rates of substitution (1 ). Let u(:1:1, 2:2) = 4239-45336. Calculate the MRS between :31 and x2. 0 Utility functions and preferences. A consumer is choosing between three bundles composed of different amounts of pears and Snickers bars. Bundle 0: contains 3 pears and 3 snickers. Bundle 1) contains 5 pears and 5 snickers. Bundle 0 contains 1 pear and 9 snickers. Find a utility function that (1) is consistent with these preferences if b > a and c > b, and (2) has a strictly decreasing MRS between ' the 2 goods
