Solve the exponent
The population in 2001 is 23.1 million
Solving (b): When will it reach 28.3 million
This implies that:
So, we have:
Divide both sides by 23.1
Take natural logarithm of both sides
Rewrite as:
So:
Make t the subject
Add the value of t to 2013 to get the actual year
It will reach 28.3 million in 2013
