Answer:
6 book purchases.
Step-by-step explanation:
As the bookstore sells frequent buyers discount cards at $ 12, which make the books that usually cost $ 9 cost $ 7, to determine from how many books a card-holder and a common buyer will spend the same amount of money is necessary perform the following calculation:

Non-card holder = 9 x 6 = 54
