Answer:
-8.9% rounded to the nearest tenth.
Step-by-step explanation:
The formula for percent change over a time period is:
p=n-o/o. x 100.
25800-23500=2300
2300/23500=0.0891472868%
Round it to the nearest tenth to get 8.9%
Multiply by 100 to get 8.9%
Make it negative because the population went down.
