Urgently needed.. Asap I. Formulate the Linear Programming Model, to identify the Decision Variables, Objective Function andSubjects to constraints of the following problems. Analyze each problem carefully.1. A problem often of concern to managers in processing industries is blending. Lisa Rankin mustdetermine the proper amount of each raw material to purchase for the production of a certain product.Each gallon of the finished product must have a Combustion Pt of atleast 220°F. In addition, theproduct's Gamma content (Causes hydrocarbon pollution) cannot exceed 6% of volume and theproducts Zeta content (cleans the internal moving parts of engines) must be atleast 12% by volume. 3Raw materials are available. Each raw mat’l has a different rating on these characteristics:RAW MATERIAL|C280CharacteristicsABCombustion PT20018043Gamma ContentZeta Content1020108Raw material A costs $0.60 per gallon, B & C costs $0.40 & $0.50 per gallon respectively. Theprocurement manager wants to minimize the cost of raw materials per gallon of product. Use linearprogramming to find the optimal proportion of each raw material for a gallon of finished product.

Another way to derive a demand function is to break the market into segments and identify a low price, a medium price, and a high price. For each of these prices and market segments, we ask company experts to estimate product demand. Then we use Excels trend curve fitting capabilities to fit a quadratic function that represents that segments demand function. Finally, we add the segment demand curves to derive an aggregate demand curve. Try this procedure for pricing a candy bar. Assume the candy bar costs 0.55 to produce. The company plans to charge between 1.10 and 1.50 for this candy bar. Its marketing department estimates the demands shown in the file P07_47.xlsx (in thousands) in the three regions of the country where the candy bar will be sold. What is the profit-maximizing price, assuming that the same price will be charged in all three regions?
In the problem on excel : 1.What are the decision variables 2.What is the objective functions 3. What are the constraints and explain A used t company, owned by Musa in Ottawa sells 7 different brands covering 3 different products. These are 4 Brands of Cars: Toyota, Honda, Chevrolet and BMW; 2 brands of Motorcycles: Suzuki and Yamaha, and 1 brand of Sailboats: Amel. Musa knows that his sales floor which he will display his products is 70,000 square feet, and that a Car takes 60 square feet of space, a motorcycle takes 20 square feet of space, and a sailboat takes 800 square feet of space. The profit that can be made for selling each of 7 different items is listed below: ITem Profit per unit Car - Toyota $2800 Car - Honda $3900 Car - Chevrolet $2,100 Car - BMW $5000 Motorcycle - Suzuki $1,000 Motorcycle - Yamaha $2,250 Sailboat - Amel $9,500 The transportation company is trying to determine how many of each item to order to maximize profit, given the following restrictions: 1.…
4 Sunco processes oil into aviation fuel and heating oil. Itcosts $40 to purchase each 1,000 barrels of oil, which isthen distilled and yields 500 barrels of aviation fuel and 500barrels of heating oil. Output from the distillation may besold directly or processed in the catalytic cracker. If soldafter distillation without further processing, aviation fuelsells for $60 per 1,000 barrels, and heating oil sells for $40per 1,000 barrels. It takes 1 hour to process 1,000 barrels ofaviation fuel in the catalytic cracker, and these 1,000 barrelscan be sold for $130. It takes 45 minutes to process 1,000barrels of heating oil in the cracker, and these 1,000 barrelscan be sold for $90. Each day, at most 20,000 barrels of oilcan be purchased, and 8 hours of cracker time are available.Formulate an LP to maximize Sunco’s profits.

The board of directors of General Wheels Company is considering seven large capital investments. Each investment can be made only once. These investments differ in the estimated long-run profit (net present value) that they will generate as well as in the amount of capital required, as shown by the following table. Investment Opportunity 1 2 3 4 5 6 7 Estimated Profit ($million) 17 10 15 19 7 13 9 Capital Required for Investment Opportunity ($million) Capital Available ($million) 1 2 3 4 5 6 7 Capital 43 28 34 48 17 32 23 100 The total amount of capital available for these investments is $100 million. Investment opportunities 1 and 2 are mutually exclusive, and so are 3 and 4. Furthermore, neither 3 nor 4 can be undertaken unless one of the first two opportunities is undertaken. There are no such restrictions on investment opportunities 5, 6, and 7. The objective is to select the combination of capital investments that will maximize the total estimated long-run…

1. Explain your observations about the optimal solution returned by the Solver. 2. If the company has budget to increase the total capacity by 1,000 units, at which plant would you recommend them to expand? What would be total cost savings (i.e., potentially more reduction in the total costs) with this expansion? Refer to the sensitivity report and explain your answer. (Copy and paste the constraints section of the sensitivity report here.) 3. Suppose that the Atlanta plant had to reduce capacity by 1,000 units to repair and renovate. How much would this cause the total (optimized) transportation costs to increase? Refer to the sensitivity report and explain your answer. All i need is help with explaing these answers using the sensitivy reports and answer reports.
