At the beginning of last year (2021), Richter Condos installed a mechanized elevator for its tenants. The owner of the company, Chris Richter, recently returned from an industry equipment exhibition where he watched a computerized elevator demonstrated. He was impressed with the elevator's speed, comfort of ride, and cost efficiency. Upon returning from the exhibition, he asked his purchasing agent to collect price and operating cost data on the new elevator. In addition, he asked the companys accountant to provide him with cost data on the companys elevator. This information is presented below.
