Answer:
20 million
Step-by-step explanation:
Given : The human population doubles approximately every 50 years
To Find: If there were 2.5 million people in 1950 how many people are forecasted to populate the earth in 2100
Solution:
Equation for growth = [tex]y=ab^x[/tex]
where a is the initial amount
y is the amount after x years
x denotes the time
A.T.Q
[tex]y=2.5(2)^{\frac{2100-1950}{50}}[/tex]
[tex]y=20[/tex]
So, 20 million people are forecasted to populate the earth in 2100 .
