PhotoQuik is a film developing company. Customers mail their undeveloped rolls of film to the company and receive the completed photographs in return mail. The PhotoQuik facility is built and staffed to handle the processing of 100,000 rolls of film per year. The lab facility cost $330,000 to build and is expected to last 20 years. Processing equipment cost $592,500 and has a life expectancy of five years. Both facility and equipment are depreciated on a straight-line basis. PhotoQuik has five salaried processing technicians, each of whom is paid $15,000. In addition to the salaries, facility, and equipment, PhotoQuik expects to spend $400,000 for chemicals, photo paper, envelopes, and other supplies (assuming 100,000 rolls of film are processed). Last year, 96,000 rolls of film were processed.
