2.4 You are an executive for a firm like VCA Antech, which operates over 600 animal hospitals in the United States. Each hospital is treating the desired number of cases per day. At each hospital, you estimate that hiring another veterinarian enables the location to treat 20 additional cases per day and firing one decreases the number of cases treated by 20 per day. Hiring another veterinary assistant enables the location to treat 10 more cases per day, and firing one decreases the number of cases treated by 10 per day. Finally, hiring another veterinary technician enables the location to treat 15 more cases per day, and firing one decreases the number of cases treated by 15 per day. A veterinarian is paid $300 per day, a veterinary assistant is paid $100 per day, and a veterinary technician is paid $150 per day. Are your hospitals minimizing the cost of treatment? If so, explain why. If not, identify the change(s) that you should make.
