The youth clothing store works 6 days a week, 12 hours a day. Time blocks 9:00- 13:00 13:00- 17:00 17:00- 21:00 Monday Tuesday Wednesday Thursday 10 10 12 10 15 12 12 14 11 14 17 16 Friday 15 18 25 Saturday 15 18 20 There are three types of employees: regular 9:00 to 17:00, 13:00 to 21:00 regular and part-time working a block of 4 Hrs.

Regular employees work at $ 12.00 an hour and part-time employees are paid at $ 8.00 an hour. By agreement with the union, the number of partial employees must not exceed 20% of the total number of employees. Formulate this problem as one of linear programming
