Answer:
160,000
Step-by-step explanation:
Estimations like this usually involve rounding to easy numbers to multiply. You could do this in a number of ways depending on your ability to keep track of factors in your head, but the easiest way (and what I assume your teacher is looking for) is to round to the nearest, largest-power-of-ten, which in this case is the hundreds. 786 is closest to 800, and 217 is closest to 200, and 200*800 is 160,000. No calculator required is the key. You can also be slightly more sure that this is <em>reasonable</em> because you rounded up for one and down for the other, approximately by the same amount, too.
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:
Using exponential:

Now, we can find the estimated population in 2015:
Therefore, the population in 2015 will be 165 million.
