Answer:

  451.2 million

Step-by-step explanation:

We can write the exponential growth equation as ...

  N(t) = 231·e^(0.0103(t-1980))

Then N(2045) = 231·e^(0.0103(2045-1980)) = 231·e^0.6695 ≈ 451.2

The population is predicted to be 451.2 million in 2045 if the growth continues at the same rate.
