WBE Corp. manufactures a wide range of equipment. The company's biggest seller is the Whatchamacallit, which sells for $4,530 each. Starting in 2023 each Whatchamacallit now carries with it a two-year warranty against manufacturing defects. In addition to this warranty, customers can purchase an optional extended warranty for $1,680 extra that extends the Whatchamacallit's warranty an additional two years. From experience with similar products, WBE Corp. has determined that each Whatchamacallit sold will average $980 in replacement parts (ignore labour costs for repairs). In 2023, the company sells 600 Whatchamacallits; 250 of these customers decide to purchase the optional extended warranty. Assume the revenue is earned evenly over the two-year contract. Also in 2023, the company incurred $165,000 in total repair costs (replacement parts out of inventory).
