a library charges a fine of 5.10 for a book that has been overdue for 30 days what is the constant of proportianly that relates the amount of the fine in dollors , y to the number of days the book is overdue,x

Answer 1

To find the constant of proportionality, we can set up a proportion using the given information.

Let y be the amount of the fine in dollars and x be the number of days the book is overdue.

We are given that the fine for a book that is overdue for 30 days is $5.10. So, we have the following proportion:

5.10/30 = y/x

To find the constant of proportionality, we can solve for y in terms of x:

y = (5.10/30)*x

y = 0.17x

Therefore, the constant of proportionality that relates the amount of the fine in dollars, y, to the number of days the book is overdue, x, is 0.17.
