Answer:
5% decrease
Step-by-step explanation:
A percentage change can be calculated using the formula ...
percentage change = ((new value)/(old value) -1) × 100%
Using the given population values, we can find the change to be ...
percent change = (23221/24528 -1) × 100% = (0.947 -1) × 100%
= -5.3% . . . . . a negative change indicates a decrease
The percentage decrease in the town's population is 5%.
