Yes, it breaks down when there are no ratios that can be computed but there are still negative values in the bottom row. Yes, it breaks down when all of the computed ratios in the pivot column are equal. Yes, it breaks down at the very beginning when there are no negative values in the bottom row. No, it does not break down. (d) Does the result in part (c) imply that no solution exists for the linear programming problem and, if so, why? Yes. No single unique solution exists because the solution region is unbounded. Yes. No single unique solution exists because x can be made as large as we please. Yes. No single unique solution exists because no matter what values of x and y are selected, the P value will be negative. No. A single unique solution exists.
