A population of 1,750 cheetahs decreases by 10% per year. How many cheetahs will there be in the population after 11 years? Round your answer to the nearest whole number.
Set up the equation 1,750*(100%-10%)^11 years= 549 cheetahs.
Hope it helps!
Or... Another way to solve it is this, we can make an equation.
We know that the cheetah population is decreasing by 10% each year so each year it will be (100-10)% = (90% = 0.9) of the amount of cheetah's the previous year. Since it is going on for 11 years it's exponential.
1750 * (0.9)^11
Rounding to the nearest integer we get 549 cheetahs.
About 549 cheetahs
