c

Step-by-step explanation:

its < so the circle wouldn't be filled in. the answer would be x < - 9, so that means x is a value that is less than -9

The correct option is C = 7 + 2n.
From the question given above, we are told that, a notebook costs $7 and divider cost $2 per kg.
So if you buy one notebook, it will cost $7 and
if you buy n packages of dividers, it will cost $2 * n = 2n.
If you add all the costs of the items together, you will have
Cost [C] = 7 + 2n.
