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
