The domain tells you about the independent variable, number of payments made. So the inequality should be

smallest number of payments made ≤ variable representing payments ≤ largest number of payments made.

The smallest number of payments is 0 and the largest is 8, so you'll have
$$0 ≤ variable ≤ 8$$
