Answer 1

It's D. Marsha is below sea level. To get as far above sea level as she is below, she would have to move to a location 40 feet higher.

Answer 2

Apologies for the confusion. Yes, you are correct. The equation −x + 40 = x can be modeled by the real-world problem: "Marsha is below sea level. To get as far above sea level as she is below, she would have to move to a location 40 feet higher." Thank you for pointing that out.
