Hello, I need to understand what I got wrong with these problems. Picture 1 is there for reference

Andreoni-Miller preferences and a Dictator Game Consider a dictator game in which the price of giving differs from 1, as in the Andreoni and Miller experiment. Specifically, let x, represent the amount of an endowment of 30 that the dictator keeps, x, the amount that the recipient receives as a result of the dictator's gift, and suppose the price of giving is 0.5. Thus, the budget constraint is: * +0.5.x, =30. In addition, suppose throughout this section that the dictator has Andreoni-Miller (i.e., CES) preferences, and consider the following cases of different parameter values for the dictator's utility function.Case 1: p = -00 25. Write the dictator's utility function, u , for this case. 26. Write the equation that represents the relationship between x, and x, at the optimum. That is, for this dictator, write an equation with x on the left and x, on the right. 27. Solve for the optimal value of x , x . Hint: use the budget constraint and the result from the previous problem. ng Solve for the optimal value of X2 , x2 . Check that x, and x* satisfy the budget constraint. 29. What is the value of the dictator's utility, U. , at this optimum
