after using the linear regression feature on my calculator I have estimated that a car 8 years after being purchase would have a value of about $5,404.66
The intercepts of the third degree polynomial corresponds to the zeros of the equation
y = d*(x-a)*(x-b)(x-c)
Where a, b and c are the roots of the polynomial and d an adjustment coefficient.
y = d*(x+2)*(x)*(x-3)
Lets assume d = 1, and we get
y = (x+2)*(x)*(x-3) = x^3 - x^2 - 6x
We graph the equation in the attached file.

Answer: Choice A)
Take her phone and laptop with her to get something to eat
=======================================================
Explanation:
It's always a good idea to keep a close watch on your stuff in a public place like an airport. This is for 2 reasons:
- You don't want your stuff stolen and/or damaged
- You don't want anyone to mistake your stuff for a security threat (unfortunately we are in the age of post 9/11 where such a thing is a valid concern)
So that's why choice A is the best answer here.
Choice B and C are bad ideas, because of the items mentioned above. Choice D could work but Marnie would have to trust that stranger, which may be a very bad idea. Ideally the stranger would be trustworthy, but there's no way of her knowing for sure. So it's better to go on the side of caution and rule out choice D.
