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?
(–3, –0.90)
(–2.5, –0.75)
(4.5, 1.35)
(8, 2.40)

Since y represents the total fee and x represents the number of days late, our equation would be y = 0.30x.

Now since x represents a number of days, it should be a positive integer. This is because of course, we don't count a negative number of days late, and the library doesn't charge for late half-days, for example.

From the given points, only (8 , 2.40) has a positive integer for x. We can check that 2.40 = (0.30) x 8, so it also fits the equation.

Hope this helps!
