Step Costs, Relevant Range J. Klompus, Inc. produces industrial machinery. J. Klompus has a machining department and a group of direct laborers called machinists. Each machinist is paid $25,000 and can machine up to 500 units per year. Klompus also hires supervisors to develop machine specification plans and to oversee production within the machining department. Given the planning and supervisory work, a supervisor can oversee three machinists, at most. Klompus's accounting and production history reveal the following relationships between units produced and the costs of direct labor and supervision (measured on an annual basis): Required: 1. Based on the information provided, select two graphs: one that illustrates the relationship between direct labor cost and units produced, and one that illustrates the relationship between the cost of supervision and units produced. Graph of direct labor cost: c. a. Direct Labor Cost Direct Labor Cost Graph of cost of supervision: c. u. Cost of Supervision Cost of Supervision The correct answer is 3. Suppose that the normal range of activity is between 2,400 and 2,450 units and that the exact number of machinists is currently hired to support this level of activity. Further suppose that production for the next year is expected to increase by an additional 400 units. If there is no increase, enter "0". How much will the cost of direct labor increase? How much will the cost of supervision increase? 4 4. Briefly explain how data visualization methods (e.g., tabular, graphical, and textual) affect a person's ability to detect or interpret cost behavior patterns in a set of data. Textual visualization can be helpful for presenting data, most cost behavior patterns likely more effectively presented using tabular and, especially graphical, data visualization techniques
