Question: Dave Ladouceur owns a catering company that prepares banquets and

Dave Ladouceur owns a catering company that prepares banquets and parties for both individual and business functions throughout the year. Mr. Ladouceur’s business is seasonal, with a heavy schedule during the summer months and the year-end holidays and a light schedule at other times. During peak periods there are extra costs. He shuts down in January to repair and maintain and clean.
One of the major events Mr. Ladouceur’s customers request is a cocktail party. He offers a standard cocktail party and has developed the following cost structure on a per-person basis.
Mr. Ladouceur is quite certain about his estimates of the food, beverages, and labour costs but is not as comfortable with the overhead estimate. This estimate was based on the actual data for the past 12 months, presented below. These data indicate that overhead expenses vary with the direct labour-hours expended. The $15.70-per-hour estimate was determined by dividing total overhead expended for the 12 months by total labour-hours.
Mr. Ladouceur has recently become aware of regression analysis. He estimated the following regression equation with overhead costs as the dependent variable (y) and labour- hours as the independent variable (X):
y = $31,886 + $9.45X + e

3. What is the range within which Mr. Ladouceur can be confident of the values of a and b? 4. Mr. Ladouceur:has- been asked to prepare a bid for a 200-person cocktail party to be given next month. Determine the minimum bid price that Mr. Ladouceur would be willing to submit to earn a positive contribution margin using his estimate and the results of the linear regression analysis.
