Submit Solver solution to problem 18 from chapter 12. You may use the template provided in Excel file Electrical Power Distribution (Problem 18 Chapter 12) or create your own solution from scratch using the AggiePower.xlsx. Remember that you need to have a formula for cost minimization - use SUMPRODUCT. For question a develop the solution on a sheet named Model1, rename the sheet with answer to question b Model2. For question a and b generate Solver's Answer and Sensitivity reports. 8. Power Distribution. Aggie Power Generation supplies electrical power to residential customers for many U.S. cities. Its main power generation plants are located in Los Angeles, Tulsa, and Seattle. The following table shows Aggie Power Generation's major residential markets, the annual demand in each market (in Megawatts or MW), and the cost to supply electricity to each market from each power generation plant (prices are in $/MW ). a. If there are no restrictions on the amount of power that can be supplied by any of the power plants, what is the optimal solution to this problem? Which cities should be supplied by which power plants? What is the total annual power distribution cost for this solution? b. If at most 4,000 MW of power can be supplied by any one of the power plants, what is the optimal solution? What is the annual increase in power distribution cost that results from adding these constraints to the original formulation
