Klein industries optimization model | Calculus homework help

Need this back in 12 hours or less.

This is an Excel and a APA paper report explaining the “solver process”.

APA paper to explain all your findings together with your Excel Worksheet to demonstrate you have set up the Solver correctly. In the paper, you also need to explain how you set up the LP model to solve this case study.

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.
