Please, I need the graph drawn in a way I can copy to excel

What is the optimal solution for this problem, i.e., what are the optimal x1 and x2values and the corresponding earnings level?

Briefly explain how you would determine the dual price of the advertising budget constraint. (Alternatively, calculate the dual price and show the steps taken.)

If the rental limit constraint is decreased from 50 to 40, by how much will the monthly earnings change?

Several assumptions must implicitly be made to formulate and solve this problem using a linear program. Identify at least one LP assumption which is violated in this context, i.e., which may not be appropriate when the decision variables relate to the number of storage units developed.

Personal Mini Warehouses is planning to expand it successful Nashua business into Lowell. In doing so, the company must determine how many storage rooms of each size to build. The problem has been formulated as a linear program (LP), as follows: Where x1 is the number of large spaces developed, and x2 is the number of small spaces developed. a. Graph all of the constraints in the space below and identify the feasible region for this LP. Personal Mini Warehouses is planning to expand it successful Nashua business into Lowell.
