For this question, it wants us to write a formula that models the car's value, y, and dollars after x years.
00:11
And they're telling me that the car's value started out at $45 ,000, and it's depreciating, so the value is decreasing by a value of $5 ,000 a year.

So if i want to write it, it would be y would be the car's value in dollars, and started out at $45 ,000, and it's depreciating, so it's decreasing.
00:33
By $5 ,000 per year and years is x in this case.
00:40
The next part of the question wants us to find out after how many years will the car's value be $10 ,000.
00:47
So what i'm going to do is i'm going to set this equation that i just found equal to $10 ,000 and then i'm going to solve for x, which is years...
