Linear Programming:Decision variables, objective function, constraints, sign restriction Exercise 1. A perfumery produces two scents – lavender and rose. These perfumes are pro-duced via two processes. Process A requires 2 hours of labor and 1 lb of raw material to produce2 oz of lavender and 1 oz of rose. Process B requires 3 hours of labor and 2 lb of raw materialto produce 3 oz of lavender and 2 oz of rose. 60 hours of labor and 40 lb of raw material areavailable. Demand for lavender is unlimited, but only 20 oz of rose can be sold. Lavender sellsfor 16 oz, and rose sells for 14 oz. Any unsold rose perfume must be shipped to a vendor inParis at a cost of 2 oz. Formulate an LP to maximize total sales less shipping costs.

As per the question, we are asked to assist a perfumery in maximizing their sales revenue minus…

Formulate but do not solve the following exercise as a linear programming problem. Perth Mining Company operates two mines for the purpose of extracting gold and silver. The Saddle Mine costs $12,000/day to operate, and it yields 45 oz of gold and 3000 oz of silver each of x days. The Horseshoe Mine costs $14,000/day to operate, and it yields 80 oz of gold and 1250 oz of silver each of y days. Company management has set a target of at least 600 oz of gold and 16,000 oz of silver. How many days should each mine be operated so that the target can be met at a minimum cost C in dollars? Minimize C = subject to the constraints gold silver

Formulate but do not solve the following exercise as a linear programming problem.A division of the Winston Furniture Company manufactures x dining tables and y chairs. Each table requires 40 board feet of wood and 2 labor-hours. Each chair requires 16 board feet of wood and 4 labor-hours. In a certain week, the company has 2800 board feet of wood available and 560 labor-hours.If the profit for each table is $50 and the profit for each chair is $18, how many tables and chairs should Winston manufacture to maximize its profits P in dollars? Maximize P = subject to the constraints board feet labor-hours x ≥ 0 y ≥ 0
Hugh and his partners grow tomatoes exclusively. Although they grow many varieties, tomatoes are all that they produce for leading supermarket chains in the UK. Should they diversify into related products such as lettuce? Write a summary report, focusing on the objective function, constraints, and decision variables that are used for Linear Programming. L for box for lettuce T for box of tomato

Formulate but do not solve the following exercise as a linear programming problem. A nutritionist at the Medical Center has been asked to prepare a special diet for certain patients. She has decided that the meals are to be prepared from Foods A and B and that the meals should contain a minimum of 390 mg of calcium, 10 mg of iron, and 40 mg of vitamin C. Each ounce of Food A contains 25 mg of calcium, 2.5 mg of iron, 2 mg of vitamin C, and 6 mg of cholesterol. Each ounce of Food B contains 25 mg of calcium, 0.5 mg of iron, 5 mg of vitamin C, and 5 mg of cholesterol. How many ounces of each type of food should be used in a meal so that the cholesterol content C (in mg) is minimized and the minimum requirements of calcium, iron, and vitamin C are met? Minimize C = subject to the constraints calcium iron vitamin C x ≥ 0 y ≥ 0
