Annika was 14 days late with her book.

Step-by-step explanation:

The first four days would cost Annika 1.0 dollar (4x0.25), then we need to divide the rest of the ammount by 0.30 to calculate for how many days she paid the 0.30 dollar fine.

4.00 - 1.00 = 3.00

3.00/0.30 = 10

Therefore, Annika was 4 + 10 = 14 days late with her book.
