Question 1101932: A book club promises to send 8 books for $1, if you join the club. After you receive the 8 books, you may select more books at a rate of $19.99 per book. If you spend a total of $87.96, how many extra books did you purchase?
Answer by Boreal(15235) About Me  (Show Source):
You can put this solution on YOUR website!
number of books bought AFTER=x
Cost of those books is 87.96-8=79.96
This is 4 extra books, because $79.96/4=$19.99
Note, the wording is not good. The book club sends 8 books for $1 EACH. That is needed to make this question answerable. As written, it sounds like 8 books were for $1.
