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???

if you count attendance in "studentdays" 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.
