Question

Hannah's school hosted a book donation. There are 150 students at her school, and they donated a total of b books! Hannah donated 3 times as many as the average number of books each student donated. How many books did Hannah donate? Write your answer as an expression.

Answer 1

Total number of students = 150.

Total number of books by all students = b books.

Average of number of books each student donated = (Total number of books denotend by all students) ÷ (Total number of students).

= b÷150 books by each student or b/150.

Hannah donated 3 times as many as the average number of books each student donated.

3 times of Average of number of books each student donated = 3 * b/150

= b/50.

Therefore, the expression for number of books Hannah donate = b/50
