If I’m at 88.9% attendance and need to be at 90% how many days will it take ?

Answer 1

Ho many days are there in class?

5 days per week x 9 weeks per semester x 4 semesters per year =

180 days

This does not count holidays, hurricane and weather days, etc....

You need 90% of 180 = 162

You have 88.9% of 180 = 160.02 days

You need 2 more days

The general formula is 0.9N - 0.889 = 0.011*N

where N is the number of days

Answer 2

How many total school days are there? If you go to school 180 days, there's one answer. If you go to school 160 days, there's a different answer.

Massachusetts uses 180, so I'll solve for that.

(.90)(180) = 162 days attended

Depending on how many days you have already attended school, the difference of 162 and that number is the number of days required.

(.899)(x) = number of days you have attended so far. x = total number of school days so far.

Answer 3

It depends on how many total days so far.
