Can you do this showing and explaining all the steps in excel please? This problem is shown here with the necessary network model https://www.chegg.com/homework-help/questions-and-answers/salesman-health-proof-pharmaceutical-company-travels-week-office-atlanta-one-five-cities-s-q95978676?trackid=97189c752405&strackid=da313b79d0a5 However I need it demonstrated in Excel: Problem Statement A salesman for Healthproof Pharmaceutical Company travels each week from his office in Atlanta to one of five cities in the Southeast where he has clients. The travel time (in hours) between cities along interstate highways is shown along each branch in the following network: 1) Determine the shortest route from Atlanta (node 1) to the destination (node 6). Please define your optimization model in Excel and solve it [70 points]. 2) Assume that the network now represents six different communities in a city and that the local transportation authority wants to design a rail system that will connect all six communities with the minimum amount of track. The miles between each community are shown on each branch. Develop a minimal spanning tree for this problem [30 points].
