Consider the following linear program and answer the following questions. Max 3A + 4B s.t. −1A + 2B ≤ 7 1A + 2B ≤ 15 2A + 1B ≤ 17 A, B ≥ 0 Solve the problem using the graphical solution procedure.
Write your solutions on a separate paper and attach it to this sheet. You are welcome to share ideas with others in the class, but be sure the work you submit is your own. Part I For the following linear program, solve using the simplex method. In the table, trace the sequence of corner points in the simplex procedure. Beginning with the solution in your initial tableau, record the basic solution, and the value for z. You may not use all of the rows in the table. Corner Point (x, y) Value of z Part II Maximize z = 17x + 20y, subject to -7x+10y≤ 50 3x + 5y < 90 4x + 5y ≤ 105 x≤ 20, x ≥ 0, y ≥ 0 Increase in z Write your final tableau, and verify it represents the optimal solution. Values of Slack Variables (S1, S2, S3) Now, solve the same problem, but use column 1 as the first pivot column, instead of column 2. Record your sequence of pivots in the table below, as you did in Part I. Corner Point (x, y) Value of z Increase in z Slack Variables (S1, S2, S3) Notice that this nonstandard…
