City library charges 35 cents every day a book is late
School library charges 25 cents every day a book is late
Step-by-step explanation:
The late fees for a school library are represented by the function c=.25d where c is the total cost and d is the number of days a book is late.
The fees charged by a city library are shown in the table. Table is attached below
For the given table y intercept is 0
slope of the city library is 0.35
slope of school library is 0.25
y interept of both city and school library is 0

City library charges 35 cents every day a book is late
School library charges 25 cents every day a book is late
