Each day, 30 cents are added onto the fee.

-3 days would mean -3 * 30 cents on the fee, which is -90 cents, or -0.90.
and -2.5 charges of 30 cents would be -75 cents!
...but you can't have negative days or fees, so A and B are out of the question.

4.5 charges of 30 cents IS $1.35...
...but the library charges by day, of course.

8 charges of 30 cents would be $2.40, and both of these are realistic possible numbers.
