Ms. Pryce has 82 books. She puts 10 of them in her desk. The rest will go in her bookcases.
One bookcase has 2 shelves, and the other has 4 shelves. Write and solve an equation to find
s, the number of books Ms. Pryce should put on each shelf so that each has the same
number of books.

12 books per shelf

Step-by-step explanation:

She has 82 books and ten of them go to her desk. So she has 72 books left to to put on her shelves. There are a total of 6 selves.

So (72 books) / (6 shelves) = 12 books per shelves.

General equation:

{(total number of books) - (books go to her desk) ] / (total number of shelves)

s = number of books on shelves

t = total number of books

d = books on desk

x = number of selves

s = (t-d) / x

step-by-step explanation:

most likely the answer is a.
