Answer: 495 people
Step-by-step explanation:
As this involves the population in a future year, you can use the future value model for this:
= Population * ( 1 + rate of increase) ^ number of years
Number of years = 2020 - 2011
= 9 years
Rate of increase will be negative to show that it is a decrease.
= 567 * ( 1 - 1.5%) ⁹
= 494.9
= 495 people
