Pre algebra problem I'm stuck on :/ Can you please help me work it out I've tried to figure it out

3.
In a survey, 480 people, or 75%, said they attended a movie at least once a month. How many people were surveyed?

A.405 people
B.360 people
C.555 people
D.640 people

D. 640 People were surveyed. Here is the formula to figure this out: Rate x base = Part. In the case the rate is 75% (or .75). The part is 480. So if you divide 480 by .75 you get 640 people. Good luck to you

You're welcome. I'm glad it helped!
