. Embassy motorcycles (EM) manufactures two lightweight motorcycles designed for easy
handling and safety. The EZ-Rider model has a new engine and a low profile that make it easy to
balance. The Lady-Sport model is slightly larger uses a more traditional engine, and is specifically
designed to appeal to women riders. Embassy produces the engines for both models at its Des
Moines, Iowa, plant. Each EZ-Rider engine require 6 hours of manufacturing time and each Lady-
sport engine requires 3 hours of manufacturing time. The Des Moines plant has 2100 hours of
engine manufacturing time available for the next production period. Embassy’s motorcycle
frame supplier can supply as many EZ-Rider frames as needed. However, the Lady-Sport frame is
more complex and the supplier can provide only up to 280 Lady sport frames for the next
production period. Final assembly and testing requires 2 hours for each EZ-Rider model and 2.5
hours for each Lady-Sport model. A maximum of 1000 hours of assembly and testing time are
available for the next production period. The company’s accounting department projects a profit
contribution of $2400 for each EZ-Rider produced and $1800 for each Lady-Sport produced.
Formulate a linear programming model that can be used to determine the number of units
of each model that should be produced in order to maximize the total contribution to profit.
Find the optimal solution using the graphical solution procedure.
Which constraints are binding?

- For a given week, Debra's Coffee House has available 1728 ounces of A grade coffee and 1760 ounces of B grade coffee. These are blended into 1-pound packages as follows: an economy blend that contains 2 ounces of A grade coffee and 10 ounces of B grade coffee, and a superior blend that contains 9 ounces of A grade coffee and 2 ounces of B grade coffee. (The remainder of each blend is made of filler ingredients.) There is a $3 profit on each economy blend package sold and a $4 profit on each superior blend package sold. Assuming that the coffee house is able to sell as many blends as it makes, how many packages of each blend should it make to maximize its profit for the week?arrow_forwardHenry Lee is the Vice President of Purchasing for the consumer electronics division of the Major Electric Corporation (MEC). The company recently introduced a new type of video camcorder that has taken the market by storm. Although Henry is pleased with the strong demand for this product in the market place, it has been a challenge to keep up with MEC's distributors' orders of this camcorder. His current challenge is how to meet requests from MEC's major distributors in Pittsburgh, Denver, Baltimore, and Houston who have placed orders of 10,000, 20,000, 30,000, and 25,000 units, respectively, for delivery in 2 months (there is a 1-month manufacturing and one-month shipping lead time for this product). MEC has contracts with companies in Hong Kong, Korea, and Singapore who manufacture camcorders for the company under the MEC label. These contracts require MEC to order a specified minimum number of units each month at a guaranteed per unit cost. The contracts also specify the maximum…arrow_forwardBlue Ridge Hot Tubs manufactures and sells two models of hot tubs: the Aqua-Spa and the Hydro-Lux. Howie Jones, the owner and manager of the company, needs to decide how many of each type of hot tub to produce during his next production cycle. Howie buys prefabricated fiberglass hot tub shells from a local supplier and adds the pump and tubing to the shells to create his hot tubs. (This supplier has the capacity to deliver as many hot tub shells as Howie needs.) Howie installs the same type of pump into both hot tubs. He will have only 200 pumps available during his next production cycle. From a manufacturing standpoint, the main difference between the two models of hot tubs is the amount of tubing and labor required. Each Aqua-Spa requires 9 hours of labor and 12 feet of tubing. Each Hydro-Lux requires 6 hours of labor and 16 feet of tubing. Howie expects to have 1,566 production labor hours and 2,880 feet of tubing available during the next production cycle. Howie earns a profit of…arrow_forward
- A female bodybuilder is designing her diet leading up to a competition. To meet her macronutrient goals, she needs to consume at least 240 grams of protein and at least 30 grams of fat per day. Additionally, she needs to eat at most 120 grams of carbohydrates per day. Her goal is to meetthese goals while minimizing her sodium intake. She plans to eat only three foods: eggs, white rice, and oatmeal. Each serving of eggs has 6 grams of protein, 5 grams of fat, and no carbohydrates. Each serving of white rice has 4 grams of protein, no fat, and 40 grams of carbohydrates. Finally,each serving of oatmeal has 6 grams of protein, 3 grams of fat, and 20 grams of carbohydrates. The eggs, white rice, and oatmeal has 60, 2, and 80 units of sodium respectively. What I Have: (a) Define the decision variables.(b) What is the objective?
