Answer:
The voter percentage declined on average by 1.025% per year.
Explanation:
The difference in years between 1992 and 2000 is 8 years, and the voter percentage declined 8.2% within those eight years. So, if you are looking for the average yearly rate of change, you can divide -8.2 by 8 to see how much the voter percentage declined on average per year. (At least that is what I think the problem is asking) I hope this helps!
