Only individuals A and B live on a desert island where no production is possible. A is endowed with 12 units of good X and 18 units of good Y. B is endowed with 6 units of good X and 42 units of good Y. In the Edgeworth box, good X is measured on the horizontal axis. Individual A's utility function is so her MUX = 3Y and her MUY = 3X. Individual B's utility function is UB = 10 so his and his MUY = 5. Which of the following allocations are on the contract curve?
◦ (XA = 9, YA = 30), (XB = 9, YB = 30)
◦ (XA = 10, YA = 28), (XB = 8, YB = 32)
◦ (XA = 12, YA = 24), (XB = 6, YB = 36)
◦ None of the above.
