Hannah has 127 books in her collection. Her school is hosting a book donation. There are z students at her school, and they each plan to donate the same number of books and reach a total donation of 300 books! How many books will Hannah have in her collection after her donation? Write your answer as an expression.
Lets say each student donates x books;
There are z students. Therefore z * x =300
x = 300/z
Hannah is left with 127 - 300/z books after donating.
Answer:
b/50
Step-by-step explanation: There were 150 students who donated a total of b books.
The students donated an average of b/150 books each.
Hannah donated 3 times as many books as the average.
b/150 * 3 = b/50
Hannah donated b/50 books.
