The bank is working to develop an efficient work schedule for full-time and part-time tellers. The schedule must provide for efficient operation of the bank, including adequate customer service, employee breaks, and so on. On Fridays, the bank is open from 9:00 A.M. to 7:00 P.M. The number of tellers necessary to provide adequate customer service during each hour of operation is summarized here.

Time	No. of Tellers	Time	No. of Tellers
9:00 a.m.-10:00 a.m.	6	2:00 p.m.-3:00 p.m.	6
10:00 a.m.-11:00 a.m.	4	3:00 p.m.-4:00 p.m.	4
11:00 a.m.-Noon	8	4:00 p.m.-5:00 p.m.	7
Noon-1:00 p.m.	10	5:00 p.m.-6:00 p.m.	6
1:00 p.m.-2:00 p.m.	9	6:00 p.m.-7:00 p.m.	6

Each full-time employee starts on the hour and works a 4-hour shift, followed by a 1-hour break and then a 3-hour shift. Part-time employees work one 4-hour shift beginning on the hour. Considering salary and fringe benefits, full-time employees cost the bank $15 per hour ($105 a day), and part-time employees cost the bank $8 per hour ($32 per day).
