Ruth 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 Ruth paid for the book when she returned it x days after the due date:

2 + 0.25x

What does the second term of the expression represent?

Respuesta :

0.25= the fee charged for everyday the book was late, and the x= the number of days, where as 2 is the rental fee.

The second term of the expression which is 0.25x is the variable cost which is the extra amount paid for being late.

The expression 2 + 0.25x represents the amount that Ruth paid for the book.

It should be noted that the fixed cost is represented by 2 while the 0.25 represents the variable cost which is the late fee. Also, the x represented the number of days for being late.

In conclusion, the second term of the expression represents the amount that was charged for being late.
