00:01
So we have a population of a town that's increasing.
00:03
And so it wants to know how much do the population grow between 2013 and 2017.
00:10
So to do that, we're going to subtract the two population values, which i think i wrote one of them down wrong.
00:19
2134, i did.
00:21
So we're going to take 2134 minus 1431.
00:26
So it's going to be 307.
00:28
So it increased by 703.
00:31
How long did it take? well, let's subtract the years.
00:36
It took four years.
00:38
What is the average population growth per year? so we're going to take the change, 703, and divide that by four.
00:45
So it's going to go 1, 4, 30, 7, 28.
00:50
We're going to get, that's going to be 23, 5, 20.
00:55
Then we're going to say 30 at a 0.
00:58
This is going to be 7, 28, then 20.
01:02
So the average rate was 175 .75 .75.
01:07
What was the population in the year 2005? well, how many years prior to 2013 was that? that's eight years.
01:18
So we're going to take and subtract that 175 eight times...
