Please solve Problem 5 correctly

Problem 5: Consider the following problem. MaximizeZ=20x1+c2x2,subjectto3x1+a12x2605x1+a22x2120 and x10,x20, where x1 represents the level of activity 1 and x2 represents the level of activity 2 . The values of c2,a12, and a22 have not been determined yet. Only activity 1 needs to be undertaken soon whereas activity 2 will be initiated somewhat later. There are two different, but equally likely, scenarios that could unfold between now and the time activity 2 is undertaken that would lead to different values for c2,a12, and a22, as listed below. Scenario 1: c2=40,a12=4, and a22=7 Scenario 2: c2=10,a12=1, and a22=3 The goal is to use all of this information to choose a value for x1 now and to simultaneously determine a plan for choosing a value of x2 later after seeing which scenario has occurred. Use stochastic programming with recourse to formulate the appropriate model for this problem and find the optimal solution. Then describe the corresponding optimal plan in words
