16 5 points In an economy there are two individuals, A and B, and in total there are 10 units of good X and 10 units of good Y. Individual A's utility is given by U(XA YA) = 2XA + 3YA', while individual B's utility is U(XB YB) = 2XB + 3Yp-. What is an expression for the contract curve in this case? O YA = 10/3 O YA = 5 XA = 10/3 O XA = 5
