Answer:
24.1 billion
Step-by-step explanation:
One way to write the logistic function is ...
P(t) = AB/(A +(B-A)e^(-kt))
where A is initial value (P(0)), and B is the carrying capacity (P(∞)). We are told to use relative population growth in the 1990s as the value for k.
In billions, we have ...
A = 5.3
B = 100
k = 0.02/5.3 ≈ 0.003774 . . . . . relative growth rate at 20 M per year
t = 2450 -1990 = 460
![P(t)=\dfrac{530}{5.3+94.7e^{-0.003774t}}\\\\P(460)=\dfrac{530}{5.3+94.7e^{-1.73604}}\approx \boxed{24.1\quad\text{billion}}](https://tex.z-dn.net/?f=P%28t%29%3D%5Cdfrac%7B530%7D%7B5.3%2B94.7e%5E%7B-0.003774t%7D%7D%5C%5C%5C%5CP%28460%29%3D%5Cdfrac%7B530%7D%7B5.3%2B94.7e%5E%7B-1.73604%7D%7D%5Capprox%20%5Cboxed%7B24.1%5Cquad%5Ctext%7Bbillion%7D%7D)
