Answer:
= -33
Step-by-step explanation:
Number of days from Monday to Saturday = 6
Attendance on Monday to Saturday = 3 4
Attendance on Monday to Saturday = 3 4 * 6 = 2 0 4
Number of days from Monday to Thursday = 4
Attendance on Monday to Thursday = 3 3
Attendance on Monday to Thursday = 3 3 * 4 = 1 3 2
Number of days from Thursday to Saturday = 3
Attendance on Thursday to Saturday = 3 5
Attendance on Thursday to Saturday = 3 5 * 3 = 1 0 5
2 0 4 - 1 3 2 - 1 0 5 = - 3 3
