There are 150 students in Hannah's school.
Sum of books donated by the students =b.
Average books donated by each student =[tex]\frac{b}{150}[/tex]
It is given Hannah donated 3 times as many books each student donated.
Number of books donated by Hannah= [tex]3 times \frac{b}{150} = \frac{b}{50}[/tex]
The expression of the number of books donated by Hannah= [tex]\frac{b}{50}[/tex]
The number of books donated by Hannah is given by x/50.
Given
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.
What is the average donated by each student?
The average denoted by each student is given by the sum of all the books by the total number of students in the class.
Let, x be the sum of books donated by the students.
Then,
The average value of the books donated by each student is;
[tex]\rm Average = \dfrac{Total \ number \ of \ books\ donted}{Total \ number \ of \ students}\\\\Average=\dfrac{x}{150}[/tex]
Therefore,
Hannah donated 3 times as many as the average number of books each student donated.
[tex]\rm \text{Number of books donated by Hannah's } = 3\times \dfrac{x}{150}\\\\ \text{Number of books donated by Hannah's } = 1\times \dfrac{x}{50}\\ \text{Number of books donated by Hannah's } = \dfrac{x}{50}\\\\[/tex]
Hence, the number of books donated by Hannah is given by x/50.
