The population of the world was 5.7 billion people in 1995 and 6.2 billion in 2008. Assuming exponential growth by what year will the population reach 11 billion?
The Attempt at a Solution
i started by trying to find R
but am not sure the my way is right ,,, i started by 6.2/57 = 62/57
then i divided it by 13 ,, it's the difference between 2008 and 1995
,,, so (62/57)/13 = 62/741 ,,,, then i multiply it by 100 to get the percentage = 8.367
are my steps right until now ?
