<u>Answer:</u>
32 students
<u>Step-by-step explanation:</u>
We are given that at the beginning of a class period, half of the students in a class go to the library and half of the remaining to the computer lab.
Given that there are 8 students remaining, we are to find the total number of students in the class initially.
At beginning = students
After half of them leave = students
After half of the remaining leave = students
So,
x = 32
Therefore, there were 32 students in the class originally.
