Answer:
Inequality for each group is [tex]x \ge 3[/tex] where x is the number of students in a group.
The inequality for the entire class is [tex]8x \ge 24[/tex]
There are at least 24 students in the class.
==============================================================
Explanation:
x = number of students per group
We have at least 3 students per group, which means x = 3 is the lowest we can go. This forms the inequality [tex]x \ge 3[/tex]
Use the multiplication property of inequality to multiply both sides by 8 because we have 8 equal groups
[tex]x \ge 3\\\\8*x \ge 8*3\\\\8x \ge 24\\\\[/tex]
There are at least 24 students in the class. In other words, there are 24 or more students in the class.
