EcoBrite Labs performs tests on water samples supplied by outside companies to ensure that their waste water meets environmental standards. Customers deliver water samples to the lab and receive the lab reports via the Internet. The EcoBrite Labs facility is built and staffed to handle the processing of $100,000$ tests per year. The lab facility cost $$150,000$ to build and is expected to last $10$ years and will have no salvage value. Processing equipment cost $$245,000$ and has a life expectancy of five years and will have no salvage value. Both facility and equipment are depreciated on a straight$-$line basis. EcoBrite Labs has four salaried laboratory technicians, each of whom is paid $$31,000.$ In addition to the salaries, facility, and equipment, EcoBrite Labs expects to spend $$49,000$ for chemicals and other supplies $($assuming $100,000$ tests are performed$).$ Last year, $80,000$ tests were performed.
