Answer 1

Answer:

Step-by-step explanation: Consider given graph. This graph represents the fine dependence on number of days.

As you can see after 20 days the fine is constant. Then Christen returned the book to the library after 21 days (the previous day was 20th, when the fine starts to be constant).

The only number that is greater or equal than 21 is number 22.

Answer: correct choice is D - 22
