A salesperson is working on a detailing call plan with a few doctors. The expected revenues from each doctor's prescriptions are listed in the sheet "Detailing". The profit margin from each doctor differs (also provided in the sheet). The total number of calls is no more than 40 . a. Calculate the current total profit based on the effort allocation to each doctor. b. Use Excel's solver to maximize the total profit by optimizing the detailing effort. The sales calls must be non-negative integers. c. What percentage does the profit increase from optimizing detail effort?
