Final answer:
To find the average amount earned by each student, divide the total amount earned by the number of students.
Step-by-step explanation:
To find the average amount earned by each student, we need to divide the total amount earned by the number of students. In this case, there are 4 students. We can calculate the average by dividing the total of $52 by 4.
Average = Total / Number of students = $52 / 4 = $13.
So, each student earned an average of $13.
