Question

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? Round your answer to the nearest hundredth.

Answer 1

The solution to this problem will end up to be 25 x 3 = 75 + 8 = 83 / 26 = 3.192
So the number then becomes 3.20
