400 Learners attended High School of the future for 4 days this past week. If 7 students were caught violating the uniform policy, what percentage was the overall compliance for the entire week???

Answer 1

if you count attendance in "student-days" then the total attendance for the week was 1600.

1 - 7/1600 = 99.56%

If you just want to count attendance as 400, then you have to consider the possibility that at least one student was a repeat offender.
