[6 marks] For the following question, . You get 2 marks for choosing the correct answer. . You can get up to 4 marks for detailed solutions Anthony and Brandon have a utility possibility frontier that is given by the following equation: UA + 4U,2 = 100. Anthony and Brandon believe that the ideal allocation is given by maximizing an appropriate social welfare function. Anthony thinks that UA = 60 and UB = 100 is the best distribution of welfare, and presents the maximization solution to a weighted-sum-of-the-utilities social welfare function that confirms this observation. Anthony's social welfare function can be written as a) W = UA + UB b) W = UA + 5UB c) W = 5UA + UB d) W = 3UA + 5UB e) None of the above
