(A little sensitivity analysis.) You are given the final chart, with the optimal solution, for a transportation problem; note that the cell in the (4, 2) position is blank, i.e., the variable x42, with an objective coefficient (unit cost) of C42 = 18, is nonbasic. What range of values of c42 will keep the solution in the chart optimal? Hints: In this method, how do we tell that our latest solution is optimal?

Formulate the situation in matrix form. Be sure to indicate the meaning of your rows and columns. Find the requested quantities using the appropriate matrix arithmetic. A car dealer sells sedans, station wagons, vans, and pickup trucks at sales lots in Oakdale and Roanoke. The "dealer markup" is the difference between the sticker price and the dealer invoice price. The dealer invoice prices at both locations are the same: $15,000 per sedan, $19,000 per wagon, $24,000 per van, and $26,000 per pickup. The sticker prices at the Oakdale lot are $18,900 per sedan, $23,900 per wagon, $28,900 per van, and $28,900 per pickup, while at the Roanoke lot the sticker prices are $17,900 per sedan, $22,900 per wagon, $26,900 per van, and $30,900 per pickup. Represent these prices as a dealer invoice matrix D and a sticker price matrix S. Use these matrices to find the dealer markup matrix M for these vehicles at these sales lots. (Let row 1 represent the dealer in Oakdale and row 2 represent the…

allons of deionized water from each wholesaler to each distribution center is shown in the following table: Question Viewer a. Which of the following statements regarding setting up the tableau for the optimal solution for this problem is true? B. The sum of supply capacities is greater than the sum of demands, so a dummy distribution center is needed. C. The sum of supply capacities is less than the sum of demands, so a dummy wholesaler is needed. b. What is the total cost of the solution? The optimal cost is $ ((Enter your response rounded to the nearest dollar.)
Q: The Morton Supply Company produces clothing, footwear, and accessories for dancing and gymnastics. They produce three models of pointe shoes used by ballerinas to balance on the tips of their toes. The shoes are produced from four materials: cardstock, satin, plain fabric, and leather. The number of square inches of each type of material used in each model of shoe, the amount of material available, and the profit/model are shown below: Material (measured in square inches) Model 1 Model 2 Model 3 Material Available Cardstock 12 10 14 1200 Satin 24 20 15 2000 Plain fabric 40 40 30 7500 Leather 11 11 10 1000 Profit per model $50 $44 $40 a) Generate the Sensitivity Report in EXCEL for the model that you built. Interpret, in context, the Shadow Price for the Leather and the Satin constraints. Include units in your interpretations.
