In the coming production period, Muir needs to decide how many rolls of each grade should be produced in order to maximize profit. Each roll of Grade X carpet uses 52 units of synthetic fiber, requires 28 hours of production time, and needs 22 units of foam backing. Each roll of Grade Y carpet uses 45 units of synthetic fiber, requires 30 hours of production time, and needs 16 units of foam backing.The profit per roll of Grade X carpet is $205 and the profit per roll of Grade Y carpet is $155. In the coming production period, Muir has 3000 units of synthetic fiber available for use. Workers have been scheduled to provide at least 1800 hours of production time (overtime is a possibility. This means that instead of using the = or ≤ sign in the constraint you should use the ≥ sign.).

Write the ConstraintsNkrumah Farms encompasses 900 acres, and is planning to grow groundnut, soybeans, corn, and wheat in the coming planting season. Fertilizer costs per acre are: Ghs 3 for groundnut, Ghc 5 for soybeans, Ghs 2 for corn, and Ghs 1 for wheat. Nkrumah Farms estimate that each acre of groundnut will require an average of 4 hours of labour per week, while soybeans will require an average of 5 hours of labor per week. Corn and wheat will each require an average of 2 hours per week. Based on past yields and current market prices, Nkrumah Farms estimate a profit of Ghs 1200 for each acre of groundnut, Ghs 3,000 for each acre of soybeans, Ghs 2,000 for each acre of corn, and Ghs 1,000 for each acre of wheat. Nkrumah Farms cannot afford to spend more than Ghs 3,000 on fertilizer. In addition, local labor regulations require Nkrumah Farms to utilize at least 2,200 hours of labour per week.Based on past demands, Nkrumah Farms would also want to ensure that the number of acres allocated to wheat…Lakeside Boatworks is planning to manufacture three types of molded fiberglass recreational boatsa fishing (bass) boat, a ski boat, and a small speedboat. The estimated selling price and variable cost for each type of boat are summarized in the following table: Boat Variable Cost Selling Price Bass $12,500 $23,000 Ski 8,500 18,000 Speed 13,700 26,000 The company has incurred fixed costs of $2,800,000 to set up its manufacturing operation and begin production. Lakeside has also entered into agreements with several boat dealers in the region to provide a minimum of 70 bass boats, 50 ski boats, and 50 speedboats. Alternatively, the company is unsure of what actual demand will be, so it has decided to limit production to no more than 120 of any one boat. The company wants to determine the number of boats that it must sell to break even while minimizing its total variable cost. a. Formulate a linear programming model for this problem. b.
