Question-2 Arnoff Enterprises manufactures the central processing unit (CPU) for a line of personal computers. The CPUs are manufactured in Seattle, Columbus, and New York and shipped to warehouses in Pittsburgh, Mobile, Denver, Los Angeles, and Washington, D.C., for further distribution. The following table shows the number of CPUs available at each plant, the number of CPUs required by each warehouse, and the shipping costs (dollars per unit): Warehouse Pittsburgh 10 Mobile 20 10 20 Denver 5 8 Plant Seattle Columbus New York CPUS Required Angeles 9 30 10 Washington 10 6 CPUs Available 9000 4000 8000 2 1 7 4 3000 5000 4000 6000 3000 A) Find initial transportation cost (Northwest Corner Rule). B) Determine the amount that should be shipped from each plant to each warehouse to minimize the total shipping cost. C) The Pittsburgh warehouse just increased its order by 1000 units, and Arnoof| authorized the Columbus plant to increase its production by 1000 units. Will this production increase lead to an increase or decrease in total shipping costs? Solve for the new optimal solution
