Question 379957: A new mall with 2 major department stores and 55 speciality shops is being built. You are a subcontractor in charge of planning and builiding the parking lots for the mall. The planners provide you with the following information:
-The total number of parking spaces must range from 2,000 to 2,400 spaces.
-For every employess parking space there must at least 9 public parking spaces.
-There must be atleast 20 employee parking parking spaces per department store and 2 employee parking spaces per specialuty shop.
You anticipate that the building costs will be $580 per public parking space and $600 per employee parking place.
The mall planners expect that, during an average week, revenue from each public space will be at least $1,000 and from each employee parking space will be $100.
How many parking spaces of each type should be built to minimize the cost of the building of the parking lot? How many parking spaces of each type should be built to maximize weekly revenue?
