## Homework Statement

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 ?
