Hi, please teach me the solution. I cannot solve this at all.

James&Dave Warehouses is planning to expand its 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:

maximize Z = 40x1 + 30x2 (monthly earnings)

subject to: 2x1 + 4 x2 200 (advertising budget)

100x1 + 50x2 4000 (square footage required)

x1 35 (rental limit expected)

x1 & x2 0

where x1 is the number of large spaces developed, and x2 is the number of small spaces developed.

Q. 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.
