A professor has 180 students in her classes at the beginning of the semester, but 18 students withdraw from her classes before Test #3. If she has 4 classes in total and each class has an equal number of students, how many students are in each class? Round your answer to the nearest ones (i.e., one student).

Question
![### Problem Statement:
A professor has 180 students in her classes at the beginning of the semester, but 18 students withdraw from her classes before Test #3. If she has 4 classes in total and each class has an equal number of students, how many students are in each class? **Round your answer to the nearest ones (i.e., one student).**
### Solution:
1. **Initial Total Students**: 180
2. **Students Withdrawn**: 18
3. **Remaining Students**: 180 - 18 = 162
4. **Number of Classes**: 4
To find the number of students in each class, divide the remaining students by the number of classes:
\[ \text{Students per class} = \frac{162}{4} = 40.5 \]
Since the answer needs to be rounded to the nearest whole number, each class has approximately **41 students**.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdb3dca1d-57a3-4839-be8e-2a543baf6bdb%2F395c8dbf-b70c-4147-ae61-8e478211038b%2Fay3uvds_processed.png&w=3840&q=75)
