The total available labor-hours per week for Departments I, II, and III are 780, 900, and 720, respectively. The time requirements (in hours per unit) and the profit per unit for each product are as follows. ProductA ProductB ProductC Dept. I 2 1 2 Dept. II 3 1 2 Dept. II 2 2 1 Profit $18 $12 $15 If management decides that the number of units of Product B manufactured must equal or exceed the number of units of products A and C manufactured, how many units of each product should the company produce to maximize its profit? product A product B product C What is the maximum profit (in dollars)?Mr. Barrera raises goats and pigs. He wants to raise no more than 16 animals including no more than 10 goats. It will cost $25 to raise each goat and $75 to raise each pig. She will make $12 in profit from each goat and $40 in profit from each pig. She has $900 to raise animals. How many of each type of animal should she raise to maximize profit?2 ABCD company is an office equipment company that produces two types of desks: standard and deluxe. Deluxe desks have oak tops, more expensive hardware, and require additional time for finishing and polishing. Standard desks require 80 square feet of pine and 10 hours of labor, while deluxe desks require 60 square feet of pine, 18 square feet of oak, and 16 hours of labor. For the next week, the company has 5,000 square feet of pine, 750 square feet of oak, and 400 hours of labor available. Standard desks net a profit of $150, while deluxe desks net a profit of $320. All desks can be sold to national chains shops. Instructions: If the spreadsheet and Excel Solver results are given to you as follows (see Table 1 below), address the following questions: What are your Binding Constraints? What is your Optimum profit [hint: maximized profit]? What are your slack values for Pine, Oak, and Labor? Looking at the Shadow prices, how much would the objective profit increase by if you were to…

There are 25 pounds of flour and 16 pounds of sugar available, and the demand for coffee cakes is 5. Five pounds of flour and 2 pounds of sugar are required to make a pan of coffee cakes, and 5 pounds of flour and 4 pounds of sugar are required to make a pan of Danish. A pan of coffee cakes has a profit of $1, and a pan of Danish has a profit of $5. 8. In Problem 2, how much flour and sugar will be left unused if the optimal numbers of cakes and Danish are baked?

Offaly on which they grow wheat and oats. Each acre of wheat costs €105 to plant, cultivate, and harvest; each acre of oats costs €210. The Bradleys have a budget of €52,500 for next year. The government limits the number of acres of oats that can be planted to 100. The profit from each acre of wheat is €300; the profit from each acre of oats is €520. The O’Dwyers want to know how many acres of each crop to plant in order to maximize their profit. Solve the linear programming model i.e. find the optimal solution to the model so that the O’Dwyers can decide how many acres of wheat and oats they should plant. How many acres of farmland will not be cultivated at the optimal solution?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.
- Capsule Drugs manufactures two drugs. The drugs areproduced by blending two chemicals. By weight, drug 1must contain at least 65% chemical 1, and drug 2 mustcontain at least 55% chemical 1. Drug 1 sells for $6 perounce, and drug 2 sells for $4 per ounce. Chemicals 1and 2 can be produced by one of two production processes. Running process 1 for an hour requires 7 ouncesof raw material and 2 hours of skilled labor, and ityields 3 ounces of each chemical. Running process 2 foran hour requires 5 ounces of raw material and 3 hoursof skilled labor, and it yields 3 ounces of chemical 1 and1 ounce of chemical 2.

A jewelry store makes necklaces and bracelets from gold and platinum. The store has 18 ounces of gold and 20 ounces of platinum. Each necklace requires 3 ounces of gold and 2 ounces of platinum, whereas each bracelet requires 2 ounces of gold and 4 ounces of platinum. The demand for bracelets is no more than four. A necklace earns $300 in profit and a bracelet, $400. The store wants to determine the number of necklaces and bracelets to make in order to maximize profit. a.Formulate a linear programming model for this problem. b. Solve this model by using graphical analysis.xa cheese factory is making a new cheese from mixing two products a and b, each made of three different types of milk - sheep, cow and goat milk. the compositions of a and b and prices ( $ /kg) are given as follows, amount (litres) per 1000 kg of a and b sheep cow goat cost ($/kg) a 30 60 40 5 b 80 40 70 8 the recipes for the production of the new cheese require that there must be at least 45 litres cow milk and at least 50 litres of goat milk per 1000 kg of the cheese respectively, but no more than 60 litres of sheep milk per 1000 kg of cheese. the factory needs to produce at least 60 kg of cheese per week. a) explain why a linear programming model would be suitable for this case study.
