The company's controller, Carlos Pereira, has recently completed a cost study of the firm's material handling department in which he used work measurement to quantify the department's activity. The control factor unit used in the work-measurement study was hundreds of kilograms of equipment unloaded or loaded at the company's loading dock. Pereira compiled the following data.
