Answer:
161 million
Step-by-step explanation:
The growth factor over the period from 1990 to 2001 (11 years) is ...
growth factor = (159/154)
Then an exponential equation for the population growth could be ...
p(t) = 154(159/154)^(t/11)
where t is the number of years since 1990.
__
In 2005, the value of t is 15, so the model predicts a population of ...
p(15) = 154(159/154)^(15/11) ≈ 160.86 . . . . million
The population is estimated to be 161 million in 2005.
