Li Ming Yuan and Tiffany Shaden are the department heads for the accounting department and human resources department respectively at a Montreal textile firm. They have just returned from an executive meeting at which the necessity of cutting costs and gaining efficiency has been stressed. After talking with Tiffany and some of her staff members, as well as his own staff members, Li Ming discovered that there were a number of costs associated with the claims processing activity. These costs included the salaries of the two paralegals who worked full-time on claims processing; the salary of the accountant who cut the cheques; the cost of claims forms, cheques, envelopes, and postage; and depreciation on the office equipment dedicated to the processing. Some of the paralegals? time is spent in the routine processing of uncontested claims, but much time is spent on the claims that have incomplete documentation or are contested. The accountant?s time appears to vary with the number of claims processed.

Li Ming was able to separate the costs of processing claims from the costs of running the departments of accounting and human resources. He gathered the data on claims processing cost and the number of claims processed per month for the past six months. These data are as follows:

MonthClaims Processing Cost ($)Number of Claims Processed

February34,9075,700

March31,2604,900

April37,9506,100

May38,2506,500

June44,8957,930

July44,0557,514

Required:

1 Classify the claims processing costs that Li Ming identified as variable and fixed

2 What is the independent variable The dependent variable

3. Use the high-low method to find the fixed cost per month and the variable rate. What is the cost formula?

4 Suppose that an outside company bids on the claims processing business The bid price is $4.60 per claim. If Tiffany expects 75,600 claims next year, should she out- source the claims processing or continue to do it in house?
