Hi there, so for this problem we are told that the population of 8 .3 million.
00:07
So we are given the initial population 8 .3 million expected to double in 19 years.
00:18
So the population after 19 years divided by the population of that given time is equal to 2.
00:28
That is the condition that we are given.
00:30
So the population growth continues at the same rate.
00:34
What will be the population be in 30 years? so what we need to determine is the population after 30 years.
00:41
So the first thing that we need to assume in this case is that the population growth exponentially.
00:49
That means that the population has the following form, the initial population, times the exponential of a constant of proportionality times the time.
01:01
Now, we use this solution to put it in here into the condition to see what we obtain.
01:08
So we will have the population evaluated at the time plus 19 years...
