Answer:

14

Step-by-step explanation:

20 times four is 80 so we already have 12 chaperones because there are 3 chaperones for every 20 students.

20 divided by 3 is 6.6

We cannot have .6 of a chaperone so we round up to 7

And since 7 can only go into 20 two times

That means there are two more chaperones

2+12 is 14

There are 14 chaperones for the 92 students

(Hope this helps and hope im right)

Answer:

80(students)

12(chaperons)

Step-by-step explanation:

since total of 92 people in the trip including student and chaperon,add groups of 23 to become 92 or use this equation:

(20+3)×y=92

23y=92

y=92/23

y=4

therefore,

20×4=80(students)

3×4=12(chaperons)
