Answer:
B. The fixed rental for the book
Step-by-step explanation:
The library charged a fixed rental for the book and a late fee for every day the book was overdue.
[tex]2 +0.25x[/tex] shows the charges Kylie paid for the book when she returned it x days after the due date.
So, the constant term is the fixed rental.
As 0.25 is teamed up with x that is the number of days. So, 2 is the fixed rental charge.
Hence, option B is correct.
