A bird population is decreasing by 3 percent each year. Find the bird population after 6 years.

QveST [7]

Hello!

If it is decreasing by 3% each year, 18% of its population will have decreased after 6 years. As we do not have an original number, we will just say that the population is 18% less than the original.

If you want to find the exact number, multiply the original population by 0.18. Subtract the number from the original population.

I hope this helps!
