Solve this linear programming problem using the graphical method. You may use scratch paper to construct your graph and complete your calculations. (You will upload your graph and calculations after completing the exam.) The Village Butcher Shop traditionally makes its meat loaf from a combination of lean ground beef and ground pork. The ground beef contains 80% meat and 20% fat and costs the shop $ 5 per pound, while the ground pork contains 60% meat and 40% fat and costs $3 per pound. The shop wants to minimize its cost while meeting the following requirements: Fat content of the mixture must not exceed 30%. At least 40% of the mixture must be ground pork. Meat content must be at least 50% of the total mixture. No more than 60% of the mixture can be ground beef. Total weight of the mixture must be 50 pounds. How much of each kind of meat should the shop use in each pound of meat loaf? Solve this LP with the graphical method. In the box below, answer all of the following: Define the decision variables. Write the objective function. Write all constraints for the problem. List the coordinates of all extreme points of the feasible region. Identify the extreme point or points that produce the optimal value. State how many pounds of ground beef and ground pork should be used in the 50-pound mixture. Report the minimum total cost. Show the objective-function value at each extreme point or otherwise explain how you identified the optimum.    

Formulate the linear programing models. DO NOT SOLVE THEM. Be sure to clearly define each decision variable and write each constraint mathematically. A company makes two products P and Q using two machines A and B. Each unit of P that is produced requires 50 minutes processing time on machine A and 30 minutes processing time on machine B. Each unit of Q that is produced requires 24-minute processing time on machine A and 33 minutes processing time on machine B. Machine A is going to be available for 40 hours and machine B is available for 35 hours. Also, at most twice as much products Q must be made as products P. The profit per unit of P is $25 and the profit per unit of Q is $30. Company policy is to determine the production quantity of each product in such a way as to maximize the total profit given that the available resources should not be exceeded. In the box below, answer all of the following: Define all decision variables. Write the objective function. Write the constraint for Machine A. Write the constraint for Machine B. Write the constraint describing the required relationship between products P and Q. Include all non-negativity restrictions.
