Question:

As vice president of sales for a rapidly growing company, you are grappling with the question of expanding your direct sales force (from its current level of 60 national salespeople) by hiring 5 to 10 additional personnel.
How would you estimate the additional dollar cost of each additional salesperson? Based on your company's past sales experience, how would you estimate the expected net revenue generated by an additional salesperson?

How would you use these cost and revenue estimates to determine whether a sales force increase (or possibly a decrease) is warranted?
