Problem #2 (25 points) An organization has increased its profitability dramatically by using models to allocate its sales force among the company's major drugs. To guide that effort, a non-linear sales response curve is estimated for each drug. A sales-response curve relates the sale of a product to the effort expended to sell it, which in this case is measured by the number of calls made by the sales force. The following figure shows the typical shape of such a curve:

Sales Effort- S= Q+ d+ EcEffort (%) Actual Sales (% of Current) 50 25 53 50 55 75 75 100 100 125 120 150 127 175 132 200 135
