Antoine wants to get a subscription to a local library. There are two libraries, each of which charges a monthly subscription fee plus a fee for each book loaned.

The following equation gives the monthly cost (in dollars) of joining the first library as a function of the number of books loaned.

C = 10+1.5n

The monthly cost (in dollars) of the second library as a function of the number of books loaned is given by the following table of values:

2 15.50 50

8. 26

14 36.50

Which library charges more for each book loaned?
