Consider the goal programming problem minimize z = d; st 4x4 + 3x2 + di* -d;* = 60 X1 + X2 - x3 = 25 X3, X2, X3, djd > 0 where X3, Xy are the decision variables, xz is a surplus variable, and did;' are the deviational variables. Upon solving this problem is the simplex method, d;' = 15. Which of the following statements is correct? The resource constraint x1 + x2x3 = 25 is incorrect The original goal constraint was 4x1 + 3x2 = 60, and the goal CANNOT be achieved The original goal constraint was 4x1 + 3x2
