Question

Case #3
All of Mr. Bassett's science classes are going to the Natural
History Museum. A tour guide is needed for each group of
eight students. His classes have 28 students, 35 students,
22 students, 33 students, and 22 students.
How many tour guides are needed?

Answer 1

Answer:

17.5 tour guides are needed . In my idea.

Answer 2

Answer:

18

Step-by-step explanation:

If you add all of the students then divide by 8 you get 17.5. However, you can't have .5 of a tour guide, so you round up to 18.

28+35+22+33+22=140

140/8=17.5

17.5 ≈ 18 tour guides

Hope this helps!
