Final answer:
The standard quota is calculated by dividing the total number of students in all subjects by the number of classes that the teacher can teach. In this case, the teacher can teach 6 classes.
Step-by-step explanation:
The standard quota is calculated by dividing the total number of students in all subjects by the number of classes that the teacher can teach. In this case, the teacher can teach 6 classes. The formula to calculate the standard quota is:
Standard Quota = Total number of students / Number of classes
Using the given information:
Total number of students = 39 + 49 + 53 = 141
Number of classes = 6
So the standard quota is:
Standard Quota = 141 / 6 = 23.5
Rounded to three decimal places, the standard quota is 23.500.
