There are 25 students in Mrs. Venetozzi's class at the beginning of the school year, and the average number of siblings for each student is 3. A new student with 8 siblings joins the class in November. What is the new class average for number of siblings?

The new class average for number of siblings is 3 5/26 or 3.1923

Step-by-step explanation:

if the average is 3 siblings per student and there are 25 students, it means that we can calculate the number of siblings

25 * 3 = 75

we add the 8 new siblings and we also add the student

75 + 8 = 83

25 + 1 = 26

To find the new average of siblings per student, we divide the number of siblings by the number of students.

83 / 26 = 3 5/26

the new class average for number of siblings is 3 5/26 or 3.1923
