Answer:

20 million

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 =
y=ab^x

where a is the initial amount

y is the amount after x years

x denotes the time

A.T.Q


y=2.5(2)^{(2100-1950)/(50)}


y=20

So, 20 million people are forecasted to populate the earth in 2100 .
