Problem 1
Blinkies is the 24-hour hot spot in town. The work schedules start every three hours and are listed below with the number of staff members neede for each three hour period.
Staffers may be assigned 6 hour shifhts (for which they are paid $50) or 9 hour shifts (for which they are paid $65) A manager is rquired for each 25 staffers. Managers work 12 hour shifts and are paid $200 per shift. Their work schedules may also start on any of the 3 hour work periods What is the minimum cost to meet Blinky's needs and how many employees of each type will start work in each period? Could Blinky's save money by using 3 hour shifts for some employees if they had to pay $10 per hour for these staffers?
