Solve Problem and Applications:
Klein Industries manufactures three types of portable air compressors: small, medium, and large, which have unit profits of \$20.50, \$34.00, and \$42.00, respectively. The projected monthly sales are:

Small         Medium     Large
Minimum     14,000       6,200         2,600
Maximum     21,000     12,500     4,200
The production process consists of three primary activities: bending and forming, welding, and painting. The amount of time in minutes needed to process each product in each department is shown below:
Small         Medium     Large         Available Time
Bending/forming           0.4           0.7              0.8              23,400
Welding                         0.6           1.0           1.2           23,400
Painting                         1.4           2.6           3.1           46,800

How many of each type of air compressor should the company produce to maximize profit?

a.    Formulate and solve a linear optimization model using the auxiliary variable cells method and write a short memo to the production manager explaining the sensitivity information.

b.    Solve the model without the auxiliary variables and explain the relationship between the reduced costs and the shadow prices found in part a.
