Linear Programming : Simplex Method in Tableau Form

The following problem is something that needs to be put into tableau iterations, but I'm not sure of my answers on it... I'm catching on slowly, but would like to have something to use to check my work... This is a homework problem, but the homework is graded on participation, not correctness in this distance learning class. So I'd like to have the correct answer available, since I need to create my own feedback loop to make sure I'm learning the material. Please help:

Here is the problem:
______________________________________________________

Solve the following linear program by hand using the simplex method:

I have the basic tableau form written down, with the variables across the top and the constraints placed in the table. But I need to have the right answer so I can check my work, and I'm very unsure of the calculations. Please help. Thank you.

Solution Summary

A Linear Programming problem is solved using the Simplex Method in Tableau Form. The solution is detailed and well presented.

Solve the following linear program by hand using the simplexmethod:
Maximize 100 X1 + 120 X2 + 85 X3
Subject To: 3 X1 + X2 + 6 X3 <= 120
5 X1 + 8 X2 + 2 X3 <=160
X1, X2, X3 >= 0

A baby products firm produces a strained baby food containing liver and milk, each of which contribute protein and iron to the baby food. Each jar of baby food must have 36 milligrams of protein and 50 milligrams of iron. The company has developed the following linearprogramming model to determine the number of ounces of live

Consider the following linear programming problem.
MIN Z = 10x1 + 20x2
Subject to: x1 + x2 >= 12
2x1 + 5x2 >= 40
x1, x2 >= 0
What is minimum cost Z=??
Put your answer in the xxx.x (to one decimal place)

1. Consider the following linearprogramming problem:
Maximize 10x + 7y subject to:
X + 3y (less than or equal to symbol) 10
2x -y (less than or equal to symbol) 8
x (greater than or equal to symbol) 0, y (greater than or equal to symbol) 0
The initial simplextableau is:
(for choices, please see attachment)

1.Introduce slack variables and set up the initial simplextableau. Do not solve. (See attachment).
2. Determine whatever the given simplextableau is in final form. If so, found the solution to the associated regular linearprogramming problem. If not find the pivot element to be used in the iteration of the simplex meth

If it is in final form, what is the programming problem. If it is not is final form what is the pivot element?
x y u v p constant
1 1 1 0 0 6
1 0 -1 1 0 2

3 0 5 0 1 30

Consider the simplextableau:
x y z u v M

3 0 1 5 2 0 5
1 0 0 6 5 1 19
The tableau is the final one in a problem to maximize x+2y+3z. The maximum value of x+2y+3z occurs when:
a. x = 2, y=5, z=0
b. x=2
