Can you answer the question?

A small grocery store needs the following number of cash- iers during each day of a week for day (8:00 a.m. to 4:00 p.m.) and evening (4:00p.m. to midnight) shifts. The store prefers to employ full-time cashiers who work eight hours a day, five days a week, with two consecutive days off. A half- time cashier works four hours a day up to five days a week (with no requirement for consecutive days oft). Note that for each unit of cashier requirement, two half-time cashiers are needed because the periods are eight hours long. Determine the mix of full-time and half-time cashiers and schedule their work in order to minimize the total number of cashiers employed but meet the daily cashier requirements below.
