Suppose to have a linear programming problem. It is known from the optimal solution that allowable increase of the b1 is equal to 30. Initial value of b1 is 40. Choose the correct statement: a) If we change the initial value of b1 to 50 nothing will happen b) If we change the initial value of b1 to 50 the optimal basis will change c) If we change the initial value of b1 to 50 the value of objective function will change d) If we change the initial value of b1 to 20 the optimal basis will change e) None of these statements is correct
