1.Based on your Liquid Gold model and your analysis of its results, by how much (if any) would the unit shipping cost for the route from P6 to S2 need to decrease in order for that route to be included in the optimal shipping plan? (Format your answer rounded to the nearest dollar. Do not include a dollar sign.)

2.Based on your Liquid Gold model and your analysis of its results, in the optimal solution, how much material is shipped to site S2? (Format your answer rounded to the nearest unit.)

Liquid Gold, Inc., transports radioactive waste from nuclear power plants to disposal sites around the country. Each plant has an amount of material that must be moved each period. Each site has a limited capacity per period. The cost of transporting between sites is given in the accompanying table (some combinations of plants and storage sites are not to be used, and no figure is given). \begin{tabular}{lllll} Capacity & 285,922 & 308,578 & 111,955 & 208,555 \\ \hline \end{tabular} Develop and solve a transportation model for this problem. (Hint: There are a variety of ways to handle the unusable routes. One way is to add constraints to exclude those routes. Another way is to assign a very high cost to those routes so that Solver would never choose them.)
