Question

A population of 1,750 cheetahs decreases by 11% per year. How many cheetahs will there be in the population after 10 years? Round your answer to the nearest whole number.

A. 4969

B. 486

C. 546

D. 1640

Answer 1

If the population decreases 11% (0.11) per year, it means that, at each year, the population is multiplied by 100% - 11% = 89%.

Answer 2

So, after each year, the population (initially 1750) gets multiplied by 0.89. Try to calculate what it will be after 10 years.

Answer 3

You should find C (546) as your answer.
