Answer:
books.
Step-by-step explanation:
We have been given that Hannah's school hosted a book donation.
Total number of students = 150.
Total number of books donated by all students = b.
Since we know that average is calculated by dividing the sum of the values in the set by their number.
![\text{Average number of books donated by each student}=\frac{\text{Total number of books}}{\text{Total number of students}}](https://tex.z-dn.net/?f=%5Ctext%7BAverage%20number%20of%20books%20donated%20by%20each%20student%7D%3D%5Cfrac%7B%5Ctext%7BTotal%20number%20of%20books%7D%7D%7B%5Ctext%7BTotal%20number%20of%20students%7D%7D)
![\text{Average number of books donated by each student}=\frac{b}{150}](https://tex.z-dn.net/?f=%5Ctext%7BAverage%20number%20of%20books%20donated%20by%20each%20student%7D%3D%5Cfrac%7Bb%7D%7B150%7D)
Since we are told that Hannah donated 3 times as many as the average number of books each student donated. So books donated by Hannah will be:
![\text{Number of books donated by Hannah}=3\times\frac{b}{150}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20books%20donated%20by%20Hannah%7D%3D3%5Ctimes%5Cfrac%7Bb%7D%7B150%7D)
Upon simplifying we will get,
![\text{Number of books donated by Hannah}=\frac{b}{50}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20books%20donated%20by%20Hannah%7D%3D%5Cfrac%7Bb%7D%7B50%7D)
Therefore, Hannah donated
books.
