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 

= 549.17

 

Rounding to the nearest integer we get 549 cheetahs.
