There are seven home games scheduled for the;upcoming season. She must pay the Tech athletic department a vendor?s fee of;$3,000 for the season. Her stand and other equipment will cost her $4,500 for;the season. She estimates that each hot dog she sells will cost her $0.35.

The;manager of the local National Video Store sells videocassette recorders at;discount prices. If the store does not have a video recorder in stock when a;customer wants to buy one, it will lose the sale because the customer will;purchase a recorder from one of the many local competitors. The problem is that;the cost of renting warehouse space to keep enough recorders in inventory to;meet all demand is excessively high. The manager has determined that if 90% of;customer demand for recorders can be met, then the combined cost of lost sales;and inventory will be minimized. The manager has estimated that monthly demand;for recorders is normally distributed, with a mean of 180 recorders and a;standard deviation of 60. Determine the number of recorders the manager should;order each month to meet 90% of customer demand.week 2Click the link above to submit your homework.Complete the following problems from Chapter 12:Problems 8, 16, 24, 32, 36Refer to the tree diagram below to complete problem 36:MAT540;Week 2 Homework;Chapter 12;8.

The problem will be bounded and feasible. It;will also have a single optimum solution (in other words, it won?t have;alternate optimal solutions). The problem will also include a component;that involves sensitivity analysis and the use of the shadow price.You will be turning in two (2) deliverables, a short writeup of the project and the spreadsheet showing your work.Writeup.Your;writeup should introduce your solution to the project by describing the;problem. Correctly identify what type of problem this is. For example;you should note if the problem is a maximization or minimization;problem, as well as identify the resources that constrain the solution.;Identify each variable and explain the criteria involved in setting up;the model. This should be encapsulated in one (1) or two (2) succinct;paragraphs.After the introductory paragraph, write out the L.P.;model for the problem. Include the objective function and all;constraints, including any non-negativity constraints. Then, you should;present the optimal solution, based on your work in Excel. Explain what;the results mean.Finally, write a paragraph addressing the part of the problem pertaining to sensitivity analysis and shadow price.Excel.As;previously noted, please set up your problem in Excel and find the;solution using Solver. Clearly label the cells in your spreadsheet. You;will turn in the entire spreadsheet, showing the setup of the model, and;the results.Clickhereto view the grading rubric for this assignment.Week 9 homeworkMAT540;Week;9 Homework;Chapter 5;6.;The Livewright Medical Supplies Company has a total of 12 salespeople it;wants to assign to three regions ? the South, the East, and the Midwest.
