Required expression : $\dfrac{s}{24}+9$

Total number of teachers and aides for 240 students is 19.

Step-by-step explanation:

It is given that there are 9 aides in a school and 24 students for every teacher. It means the number of aides remain constant and number of teachers depend on the number of students.

24 students = 1 Teacher

1 student = $\dfrac{1}{24}$ Teachers

s students = $\dfrac{s}{24}$ Teachers

If there are s students in the school, then the expression for the total number of teachers and aides is

$\text{Total number of teachers and aides}=\dfrac{s}{24}+9$

We need to find the value of this expression for 240 students.

Substitute s=240 in the above expression.

$\text{Total number of teachers and aides}=\dfrac{240}{24}+9$

$\text{Total number of teachers and aides}=10+9=19$

Therefore, the total number of teachers and aides for 240 students is 19.
