The data about the number of minutes per day is so confusing. I'll just answer it based on what I understood from the data provided:
Monday: 480 minutes
Tuesday: 450 minutes
Wednesday: 495 minutes
Thursday: 480 minutes
Friday: 300 minutes
We need to add up all the minutes worked for the week:
480 + 450 + 495 + 480 + 300 = 2,205 minutes
2,205 minutes / 60 minutes = 36.75 hours
36.75 hours is less than the maximum number of hours worked in a week which is 40 hours.
36.75 hours translates to 36 hours and 45 minutes of work for the week.
Simple....
so we have to determine if the value is less than the base....
.... is 8<2? No.
No....
Is 3<3? No....
No.....
No.....
Y would be 8 if i’m doing this right
