Question

School guidelines require that there must be at least 2 chaperones for every 25 students going on a school trip. How many chaperones must there be for 80 students?

Answer 1

Okay! So, the minimum is 2 per 25. How many times does 25 go into 80?

Answer 2

3 times

Answer 3

Yes! It goes is evenly 3 times. So
25*3=75 students
2*3=6 chaperones

But wait! There's 5 students left over! 25/2=13 (roughly) students. So let's add in an extra chaperone (since you can't have half a human lol)

Answer 4

And a school would rather have more than the state requirement then less

Answer 5

I got 6 chaperones too, but the answer was wrong.

Answer 6

right, because its 7

Answer 7

Look at what I said. we have to add an extra chaperone to the 6, (which means 6+1=7)

Answer 8

oh, I got it now. you added they extra human.lol

Answer 9

yeah, because there was 5 extra kids. You need 1 (since 2 is for 25, 1 is for 12. 5 is less then 12, but it's closer than 25)

Answer 10

Make sense?

Answer 11

I understand now. Thanks. I will award you a medal. :)
