$28.$ The Miller$-$Porter Company sells powder coating equipment at a sales price of $$50,000$ per unit. The sales price includes

delivery, installation, and initial testing of the equipment, as well as a monthly service call for one year in which a technician

checks to make sure that the equipment is working properly and makes adjustments as needed. After the first year, customers

are given the opportunity to enter into an extended service agreement; Miller$-$Porter prices these extended service agreements

to earn an expected gross profit of $50$ percent. Given the wages paid to technicians and the time required to make a service

call, the company estimates that the cost of providing each monthly service call is $$200.$
