Question: Step Costs, Relevant Range Bellati Inc. produces large industrial machinery. Bellati has a machining department and a group of direct laborers called machinists. Each machinist can machine up to 500 units per year. Bellati also hires supervisor develop machine specification plans and to oversee production within the machining department. Given the planning and supervisory work, a supervisor can oversee, at most, three machinists. Bellati's accounting and production history shows the following relationships between number of units produced and the costs of supervision and materials handling (by machinists), measured on an annual basis:

Required: 1. Prepare a graph that illustrates the relationship between direct labor cost and number of units produced in the machining department. (Let cost be the vertical axis and number of units produced be the horizontal axis.) Would you classify this cost as a strictly variable cost, a fixed cost, or a step cost?

2. Prepare a graph that illustrates the relationship between the cost of supervision and the number of units produced. (Let cost be the vertical axis and number of units produced be the horizontal axis.) Would you classify this cost as a strictly variable cost, a fixed cost, or a step cost?

3. Suppose that the normal range of production is between 1,400 and 1,500 units and that the exact number of machinists are currently hired to support this level of activity. Further suppose that production for the next year is expected to increase by an additional 500 units. What is the increase in the cost of direct labor? Cost of supervision?
