Answer:
Assuming each class is filled to capacity, the average class size is 70.
Step-by-step explanation:
We have to find the weighted average of the number of students.
The weights are the number of classes.
We have that:
One class of 20 students
Eight classes of 60 students.
One class of 80 students.
Four classes of 100 students.
So
Assuming each class is filled to capacity, the average class size is 70.
