The managing director of a consulting group has the following monthly data on total overhead costs and professional labor hours to bill to clients

overhead cost	Billable hours
$355,000	3,000
$400,000	4,000
$425,000	5,000
$477,000	6,000
$560,000	7,000
$580,000	8,000

A) Develop a simple linear regression model between billable hours and overhead costs.

B)Interpret the coefficients of your regression model. Specifically, what does the fixed component of the model mean to the consulting firm?

C) If a special job was available requiring 4,500 billable hours that would contribute a margin of $240,000 before overhead, would the job be attractive?
