usukidoll · Answer

:/ I think it's 
14.3% x 100,236,820 first and then add that result to 100,236,820

0.143 x 100,236,820 =  approximately 14,333,865
because .26 of a person doesn't exist 
and then 100,236,820+14,333,865 = 
114,570,685 people for 2010... not 100% sure though.. feels like 70% confidence.

irishboy123 · Answer

start with this $\huge \frac{P_{2010} - P_{2000}}{P_{2000}} = 0.143$

and $\large P_{2000} = 100,236,820 $
