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.

Step-by-step explanation:
The length of the fencing is 500 foot
That means the perimeter of the playground = 500
Assume that the dimensions of it are x and y
So 2x + 2y = 500 ---- perimeter of the rectangular yard
Divide both sides by 2
x + y = 250
Now subtract the two sides by x to find y in terms of x
x - x + y = 250 - x
y = 250 - x --------(1)
Since we need to find the maximum area, let us find the area in terms of x and y
Area of the yard is A
A = xy -------- area the rectangle
Now substitute y by (1)
A= x(250 - x)
A = 250x - x^2
For the maximum area, we will differentiate A with respect to x
For maximum area equate dA/dx by zero
Since dA/dx = 0
250 - 2x = 0
Add 2x for both sides
250 - 2x + 2x = 0 + 2x
250 = 2x
Divide both sides by 2
125 = x
