PLZ DO IT IN SLOVER AND EXCEL !!!!!!!Asap

This question is hard, but all scores you get from this question will be added directly to your grand total as extra credit. If you get stuck, bypass this question and try others first. A delivery man is leaving the postal office and deliver the packages to 9 other locations (A, B, C, D, E, F, G, H, I). and then return to the postal office. In which order should he visit the locations to minimize the total distance travelled? The table below shows the distance in miles between any pairs of locations. Hint: try the "AllDifferent" constraint in the solver setup. Points breakdown: problem formulation (1\%), solver setup (0.5\%), report the correct answer (0.5%)
