The polar bear population is not declining.

ghazi · Answer

if it gets lowered by 0.3% each year then find 0.3 % of 22,500 and multiply it by 3 $$22,500*\frac{ 0.3 }{ 100 }=225*0.3=67.5$$ 
then multiply 67.5 by three =202.5 polar bears wont be there
22,500-203 =22297

ghazi · Answer

i have taken 202.5 as 203 because you cant have half polar bear, only exception is when half of the polar bear is paralysed or has lost its body :P
