We have a series of questions here related to a school population starting in 2002.
00:06
We have 1 ,8009 students.
00:09
By 2006, the population had grown to 2 ,553.
00:13
How much did the population grow between the years? so you have the right answer here is 744 because that is going to be the result of 2 ,553 minus 1 ,809.
00:26
In that time frame, that was the year 2006, minus the year 2002, and so we get four years.
00:34
My average population growth per year, the key here is per year.
00:38
So it was growing a total of 744 students over four years.
00:43
So we can average that out to 186 per year.
00:48
So 186 students per year was the growth.
00:52
What was the population in the year 2000? so 2000 happens before 2002.
00:57
So i know that as i go up in the years, i'm adding 186.
01:01
So if i think of that as in 2002, there was 1 ,809.
01:09
Okay.
01:10
So 2001 and then 2000, basically i'm going to subtract 186 two times...
