Now for some population stuff:
The world's population in 1950 was 2,555,982,611. In 1970, it was 3,706,601,448. Find the rate of growth.
* Remember our population equation:
Set it up:
What about predicting?
Can you predict what the world's population will be in 2050?
|Let's use the 1950 figure for our||:|
And we can use the growth rate we just found:
1950 to 2050 gives us t = 100...
Grab a calculator!
So, we predict that there will be 16,392,546,229 people on earth in 2050.
