An investor has $621,000 to invest in bonds. Bond A yields an average of 8% and the bond B yields 7%. The investor requires that at least 5 times as much money be invested in bond A as in bond B. You must invest in these bonds to maximize his return. This can be set up as a linear programming problem. Introduce the decision variables: x= dollars invested in bond Ay= dollars invested in bond B Compute x+y. $ . Round to the nearest cent. Investor Matt has $152,000 to invest in bonds.

One possible solution method for the machine-to-job assignment problem is the following heuristic procedure. Assign the machine to job 1 that completesjob 1 quickest. Then assign the machine to job 2 that, among all machines that still have some capacity, com-pletes job 2 quickest. Keep going until a machine has been assigned to all jobs. Does this heuristic procedureyield the optimal solution for this problem? If it does,see whether you can change the job times so that theheuristic does not yield the optimal solution.

Write a system of inequalities that describes all the given conditions, and graph the feasible region of the system. Joyce is the marketing director for a new company selling a fashion collection for young women and she wishes to place ads in two magazines: magazine V and magazine E. Joyce estimates that each one-page ad in magazine V will be read by 1.3 million people and each one-page ad in magazine E will be read by 1.2 million people. Joyce wants to reach at least 7 million readers and to place at least 2 ads in each magazine. Write a system of inequalities that describes all the given conditions. Let x represent the number of ads in magazine V and y the number of ads in magazine E. Choose the correct answer below. y X+ X y V (Round to two decimal places as needed.)

(a) u want to send these shipments as cheaply as possible. Formulate this as a linear program ( do not need to formulate it is standard inequality form) (b) all is the same as (a) but that only 220L of important chemical A are now required at warehouse 1 or 2 for storage, the company must pay transportation costs or can be disposed of at the port in which case the company paus no transportation costs but pays a disposal fee of £16 per L. You want to find how to ship or dispose of all 610L of chemical imported at the mimimum cost while still ensuring that required amounts (220L and 330L respectively) delivered to warehouse 1 and 2. Describe how to modify your linear program from previous question.
Solve the following linear programs (LPs) using the simplex algorithm. • For each tableau you obtain, write the associated BFS and its objective value. • For each LP, find the complete optimal solution set and write it using appropriate mathematical notation. Use only the information in the tableaux to justify your answer. maximize z(x1, x2, x3) = subject to -2x1 + 4.x3 + 2.x3 0

Fiserv Forum sells three types of tickets to a Milwaukee Bucks game, premium tickets at $300 each, lower level tickets at $150 each, and standard tickets at $75 each. The seating capacity is 17500. They must sell at least 8000 tickets and at least 1500 must be lower level tickets. To break- even, they must sell at least $250,000 in tickets, Write the system of inequalities describing this information on the number of tickets to be sold of each kind. Set up the linear programming problem, do not solve. (write the objective function, constraints, and nonnegative conditions)
this is a linear programming problem. one image is the required information and the other image is the question.
Q6. Consider the following linear program in standard maximization form: -5 max{r1 – x2} subject to -4 X1, 12 a) Use the Simplex Method (as seen in class) to solve the above linear program. Be sure to: o Indicate all slack and artificial variables you introduce. o Indicate the objective S of the extended tableau. o Whenever your tableau is in RRREF, indicate the current solution's values for all vari- ables. o Before pivoting, indicate the entry you plan to convert to the next pivot. o Clearly indicate why you should stop the algorithm and give a precise conclusion. b) Draw the feasible region in a fairly large and well-scaled diagram. Determine the coordi- nates of each vertex and label the vertices of the feasible region in your diagram. c) Based on the graphical approach, describe the optimal solutions of this LP (if any).
