How many books did Hannah donate?

Write your answer as an expression.

Answer 1

`(b)/(50)` 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}}`

`\text{Average number of books donated by each student}=(b)/(150)`

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*(b)/(150)`

Upon simplifying we will get,

`\text{Number of books donated by Hannah}=(b)/(50)`

Therefore, Hannah donated
`(b)/(50)` books.
