Question

Each day that a library book is kept past its due date, a $0.30 fee is charged at midnight. Which ordered pair is a viable solution if x represents the number of days that a library book is late and y represents the total fee?

Answer 1

y=.30 x is the solution to the equation

Answer 2

y=0.30x

Explanation:

Here we are given that , if a book is not returned within due date, a penalty of $0.30 is charged at mid night for every day.

Hence if the number of days by which the book is delayed is x , then total penalty charged will be

$0.30*X

=$0.30x

Let us say that the total penalty is denoted by y , Hence

y=0.30x makes a function which represents a relation between penalty imposed and the no of days for which it was delayed.

Hence the ordered pair will be (x,0.30x)
