1. The site is planning to run from 8:00 am to 5:00 pm, and you have 9,000 appointments today.  You can start drawing vaccines into syringes at 7:00 am at a rate of 1,000 per hour, and each vial provides six syringe draws, with each draw requiring 100 seconds. At 8:00 am patients start arriving at 1,250 per hour until noon, when the pace drops to a 1,000 per hour for the balance of the day.
