All right, hello.
00:01
In this question, we're told in the year 2000 what the population number of vehicles is and how fast they're growing at rate per year.
00:08
And we want to use that information.
00:10
So i'm going to write an equation for p of t.
00:12
My population is going to be my initial population, which is going to be 200 million.
00:17
And then for annual growth with a constant rate, our equation is 1 plus whatever that rate is in percent.
00:25
So 1 over 100, 1 % over 100.
00:28
And then we want to multiply that by our number of years we're looking at.
00:32
And so we can have cars on the road.
00:35
We can do the same thing.
00:37
We have initially 200 million cars.
00:41
We have 280 million people.
00:45
And then our rate of growth for the cars is 3%, so over 100.
00:50
So then i can go ahead and write this as a decimal and simplify it...
