Answer:
She donated b/50 books
Step-by-step explanation:
In this question, we are we are told 150 students donated a total of b books. The average number of books donated by each student will be:
The total number of books/ the total number of students.
The average number of books is this b/150.
Now, we are also told that Hannah donated 3 times the average number of books.
This is simply calculated by multiplying the average number of books donated by 3
This is equal to 3 * b/150 = b/50 books
Hence, Hannah donated b/650 books
It goes from (1,16) to (5,-8)
The better deal would be the 16 oz bag since it costs .24 cents an ounce.
You would be saving .2 cents on each ounce you buy.
