Answer:

B. 9xd

Step-by-step explanation:

Each CD costs $9 therefore to find total cost you multiply the cost of each CD (price) X  the number of CDs you buy (quantity).

ex.

1 CD = $9 x 1 = $9

2 CDs = $9x 2 = $18

3 CDs = $9 x 3 = $27

...and so on.

I hope this helps!
I think that it’s that because she paid $9 so she has no more money if she had $9
