Consider the goal programming problem minimize z=d 5 pts st. 4x: + 3x2 + d-d, * = 60 X1 + x2 - x3 = 25 X1, X2, X3, dj .d > 0 where x1, X2 are the decision variables, xz is a surplus variable, and did * are the deviational variables. Upon solving this problem using the simplex method, d;* = 15. Which of the following statements is correct? The original goal constraint was 4x1 + 3x2 = 60, and the goal CANNOT be achieved. The original goal constraint was 4x1 + 3x2
