Question

The average number of students per class at a middle school

is 22. There are t teachers in the school, and there is one
teacher for each class. Which equation represents the total
number of students, s, in the school?

Answer 1

s = 22t or
`(t)/(s) = (1)/(22)`, when s is students and t is teachers.

Explanation:

I. Given t = teacher, s = student

When 1 teacher per 22 students so...

s = 22t

If there're 10 teachers

s = 22(10)

= 220 or
`(t)/(s) = (1)/(22)`

Hope that help :)
