Given in the Question:
Population rate decreases at 1% every year
current population of town = 3000
Now,
Multiplying decrease rate with current population, we get:
3000× 1% = 30
Since, each year there are 30 people less in the town,
then after 05 years = 30 × 5
= 150 people.
Therefore, If the population is 3000 now , the population after 5 yeras is:
