You can put this solution on YOUR website!
Let c= cost per book
Let b= number of books bought per customer
given:
c+=+6
6b= money spent on books per customer
8= maximum books allowed
----------------
6+%3C=+6b+%3C=+48
given:
6b+%3C=+25
I'm not real sure what is wanted. I think it's
6+%3C=+6b+%3C=+25
Divide through by 6
1+%3C=+b+%3C=+4
She can buy between 1 and 4 books
