Three cleaning crews are available for a job that requires an area of 6000 square feet to be cleaned. Each cleaning crew charges a fixed cost that is only charged if the company is hired and a variable cost that is dependent on the number of square feet cleaned (see below). The job can be performed either by a single cleaner or by a combination of cleaners. Formulate and solve a mathematical programming model that will determine which crews to hire and how much (in square feet) of the job that each should do. Company A Cost = 0.15x2 + 1.5x + 2500
Company B Cost = 0.005x2 - x + 4000
Company C Cost = 0.01x2 + 2x + 5000
