Please right the answer clearly. Sometimes I can't read what you write.

(e) Change the coefficient of X, in constraint 2 to an (1) Change the coefficient of x, in constraint'l to D.1 7.1-3. Consider the following problem. Minimize W = 5y + 4y2, subject to 4y + 3y, 24 29, + y2 23 Yu + 2y, 21 + 12 22 121) + 4 and 420 If we lets straints, the m the e dual equations: (0) and Combinations of the y 20, 220 Because this primal problem has more functional constraints than variables, suppose that the simplex method has been applied di- rectly to its dual problem. If we let Xs and Xo denote the slack vari- ables for this dual problem, the resulting final simplex tableau is (2) Now you are vestigating model.

For each change, ap nly the procedure for sensitivity analysis summarized at the end of Sec, 7.1 to the dual problem (do not reoptimize), and then give wur conclusions as to whether the current basic solution for the primal problem still is feasible and whether it still is optimal. Then check your conclusions by a direct graphical ana mal problem le) Change s optimal La (1) Change YTVA PROBLEMS (a) Change the objective function to W = 3y + 5y2.
