    Answer:

    The question is unclear, but if the book store sold 9 copies total, they sold 2 yesterday.

    Step-by-step explanation:

    I am not sure how many copies were sold in total but here is how you can solve it- Get the total amount of copies and subtract the number of copies sold in total. Then get the difference and subtract 7 from it. The difference is your answer.
