To solve this problem we can make the following rule of three
6 ---> 3/4
x ----> 1
Clearing x we have:
x = (1/3/4) * (6)
x = (4/3) * (6)
x = 24/3
x = 8

Answer:
The population in 2015 will be 165 million.
Step-by-step explanation:
The exponential growth formula is given by:
Where:
a: is the initial population
r: is the rate of increase
Δt: is the time
With the initial information we can find the rate:
Using logarithm:
![ln(151) = ln(145) + 8[ln(1 + r)]](https://tex.z-dn.net/?f=%20ln%28151%29%20%3D%20ln%28145%29%20%2B%208%5Bln%281%20%2B%20r%29%5D%20)
Using exponential:
Now, we can find the estimated population in 2015:
Therefore, the population in 2015 will be 165 million.
I hope it helps you!
