To determine how many students (s) are in Cara's class based on the total number of eggs given, you can use the equation that represents the relationship between the number of students and the number of eggs each student receives.
Since each student receives 4 eggs and there is a total of 24 eggs given out, the equation can be set up as follows:
4s = 24
This equation indicates that the number of eggs (4 eggs per student multiplied by the number of students) equals the total number of eggs (24).
So, the correct answer is:
4s = 24
