The owner of the company, Ron 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 company's accountant to provide him with cost data on the company's elevator. This information is presented here. Annual revenues are $240,000, and selling and administrative expenses are $29,000, regardless of which elevator is used.
