Please see the attached file. 1.0 Given the following linear programming problem: Min Z = 2x + 8y Subject to (1) 8x + 4y 64 (2) 2x + 4y 32 (3) y 2 What is the minimal solution? Use Lingo10 or QM to solve. Include your solution screen shots 2.0 Max Z = $

Linear and Integer Programming Model

1. Consider the following linear programming model: Maximize Z=5 x1 + 4x2 Subject to 3x1+4x2≤10 X1, x2≥0 and integer Demonstrate the graphical solution of this model. 3. A tailor makes wool tweed sport coats and wool slacks.

Linear Programming : Maximum Profit

1. Shoe Manufacture A small shoe manufacturer makes two styles of trainers, a cross-training shoe and a specialist running shoe. A pair of cross-training shoes requires 1 hour machining and 2 hours assembly and makes a profit of £10. A pair of running shoes requires 1.5 hours machining and 1.5 hours assembly, and makes a p

Linear Programming : Graphical Method

Please graph the following linear programming model- Max Z = 10x + 6y 45x + 30y < = 180 3c + 8b < = 20 c, b > = 0 Please show graph and all steps in algebra to get the solution.

Linear Programming : Maximizing Profit

I am doing a linear programming model and need to graph on a grid line and I have the constraints, but do not know how to do the alegra part: Contraints: 45c + 30b= 180 3c + 8b = 20 (c, b < or equal to 0) Max profit = 10c + 6b I can not solve for the variables c and b. The answers are in the back of the book (4,0) b

Woofer Pet Foods Vitamin Content

Woofer Pet Foods produces a low-calorie dog food for overweight dogs. This product is made from beef products and grain. Each pound of beef costs $0.90, and each pound of grain costs $0.60. A pound of the dog food must contain at least 9 units of Vitamin 1 and 10 units of Vitamin 2. A pound of beef contains 10 units of Vitamin 1

Linear Programming

I wanted to make sure I came up with the correct answer. I need to find the minimum cost for the attached problem. I came up with 13,250 but not sure if that is correct. The contract calls for 10,000 hoses.
