Suppose Lan's utility function is UL(x,y) =XLby18 and Dan's utility function is Up(x,y) =XD yD2, where x; and y; denote respectively the amount of good X and of good Y consumed by person i, i=L, D. A total of 34 units of each good is available and it is to be divided efficiently between Lan and Dan. Determine how many units of good Y should Lan get if we give Dan 17 units of good Y such that the allocation is efficient. Then enter the amount of good Y below
