QUESTION 9 23 points Save Answer (23 points) Trojan Dental has four types of employees: 4 Dentists, 3 Hygienists, 1 Receptionist and 1 Scheduler. On average 100 patients arrive per day at the dental office to see either the Hygienist for their annual check-up and cleaning, or the Dentist for dental work. The Receptionist checks in each patient which takes 2 minutes. Then 65% of the patients are called in to see the Hygienists, and 35% are called in to see the Dentist.
