A car was valued at 41 ,000 in the year 1992 and 14 in 2007.
00:07
So we want to know the annual rate of change.
00:10
So we're going to do our slope here.
00:12
We're going to say 41 ,000 minus 14 ,000.
00:17
And then we're going to say 1992 minus 2007.
00:22
So that's going to end up being 27 ,000.
00:30
And then we're looking at how many years is that? 15 years.
00:33
So that's going to be a negative.
00:34
So i'm going to go 27 ,000 divided by 15 and so that's going to be a decrease of negative 8 -1 -8 -00 per year.
00:48
Now they want us to express this as a percent.
00:52
So we're looking at 1800 of the original amount.
00:56
So i'm going to take 1800 and divide that by $41 ,000 to get our percent...
