Nantucket Marine Supply is a wholesaler for a large variety of boating and fishing equipment. The company’s controller, Alan Denney, has recently completed a cost study of the firm’s material-handling department. The activity measure (independent variable) used in the study was hundreds of pounds of equipment loaded or unloaded at the company’s loading dock. Denney compiled the following data.

1. Draw a scatter diagram of the cost data for the material-handling department.
2. Visually fit a cost line to the scatter diagram.
3. Estimate the variable and fixed components of the department’s cost behavior pattern using the visually fit cost line.
4. Using your estimate from requirement (3), specify an equation to express the department’s cost behavior.
5. Estimate the material-handling department’s cost behavior using the high-low method. Use an equation to express the results of this estimation method.
6. Write a brief memo to the company’s president explaining why the cost estimates developed in requirements (4) and (5) differ.
7. Predict the company’s material-handling costs for a month when 2,250 units of activity are recorded. Use each of your cost equations to make the prediction. Which prediction would you prefer to use?Why?
