Windsor Corp. manufactures a wide range of equipment. The company's biggest seller is the Whatchamacallit, which sells for $4,510 each. Each Whatchamacallit carries with it a 2-year warranty against manufacturing defects. In addition to this warranty, customers can purchase an optional extended warranty for $1,670 extra that extends the Whatchamacallit's warranty an additional 2 years. From experience, Windsor Corp. has determined that each Whatchamacallit sold will average $970 in replacement parts (ignore labour costs for repairs). In 2017, the company sells 620 Whatchamacallits; 280 of these customers decide to purchase the optional extended warranty. Also in 2017, the company incurred $275,700 in total repair costs (replacement parts out of inventory).
