Claire shops at her local book store and recently received a $75 gift certificate for her birthday. the store recently released a new promotion. option 1: pay $9 for every book option 2: pay a $12 annual fee plus $7 per book write an equation for each option, then determine which option will be best for claire.

The best option that would be for her is to do the annual fee plus the seven dollars a book.

The reason that the annual fee is better is because you get one more book than if you do a fee everybook that is higher.

represented by the equation, below is of the yearly payment and book and the second equation is for 9 dollars a book where x is the amount of books and 75 her total budget.

       12(7x)=75-12   7x=63/7    x=9 books
        9x=75/9   x=8 books   

The answer simplified would be. -6300x
