Answer:
y=0.30x
Step-by-step 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)
