A company owns two infrared computerized surveying instruments that they use for surveying jobs as

they come in$.$ Such jobs typically arrive once every three days and typically last for four days. If a

surveying job arrives and none of the surveying instruments are available, the job goes to a competitor.

If surveying jobs are charged out at $$200$ per day how much potential business is the company losing?

Make and state any necessary assumptions required in your reasoning.
