Answer:
The publisher must sell 4,632 books in order to break even(total sold equals production costs).
Step-by-step explanation:
So the bookstores are really making $24-10.25 in profit off of each book. This equals $13.75 profit for every book sold.
So you set up an equation:
13.75x=$63,690
x=63690/13.75
x=4632
