B)If the number of days a book is overdue is doubled, how will the fine change?

In my school library you are going to be charged a fixed amount till when you return the book

Step-by-step explanation:

Borrowing of materials from library has time-lines, and special fines or penalty clause when it comes to defaulting of agreement when books are meant to be returned.

This penalty clause may differ from from one library to another.

I will cite my school library as an example.

If the time to return a book is due, the library charges a fixed amount from the due date till when ever one returns the book

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
