Answer:
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
So we can say that there is no charge for both library if they are not late
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:
multiply the first equation by 1, the second by -1 and add.
x + 2y = -16
-x - 6y = 28
--------------------
0 - 4y = 12
-4y = 12
y = -3
x + 2×-3 = -16
x - 6 = -16
x = -10
B: because 11 times N will give you how much your cost would be . Example: 11*2= $22 if you bought 2 cds it would be $22. and its continuous cause youre going up at a constant rate.
That’s the work and the answers
