Question

Joseph borrowed a book from a library. The library charged a fixed rental for the book and a late fee for every day the book was overdue. The expression below shows the charges Joseph paid for the book when he returned it x days after the due date:

2 + 0.25x

What does the coefficient of the expression represent?

The fixed rental for the book

The total late fee for the book

The late fee per day for the book

The number of days the book was overdue

Answer 1

2 + `0.25`x

notice that the total rent increases as "x" increases -
can we say "x" is the number of days the book was overdue ?

Answer 2

then, the coefficient `0.25` has to be the `late fee per day`, right ?

Answer 3

thank you
