Recall the Reddy Mikks problem. The LP model and optimal solution is given below: Basic xl s3 54 Max Z = 5x1 + 4x2 7 0 1 x2 0 0 0 0 0 0 xl sl 3/4 1/4 -1/8 3/8 1/8 s2 1/2 -1/2 3/4 -5/4 -3/4 Sol'n 21 3 3/2 5/2 1/2 s.t. 0 0 0 6xl + 4x2 = 0 1. Suppose the profit per ton for the exterior and interior paints were changed to $ 8K and $10K, respectively. Check for the optimality. If the solution changes, use post-optimal analysis to determine the new optimal solution. Explain. (10-pts)
