GPT-4o mini · Answer

Maria is at a ski resort on a mountain that is 1,500 feet above sea level. Wanting to enjoy the view, she decides to ski down the slope and descends 300 feet. After skiing, she takes a break at a scenic viewpoint that is 200 feet below her current elevation.

At this point, her elevation is modeled as:

1500 feet (starting point) - 300 feet (first descent) - 200 feet (additional descent) = 1000 feet above sea level.

However, when she decides to go back to her original position, she accidentally goes even lower than the viewpoint, reaching 1,000 feet below sea level. Thus, the final result after all descents is modeled as:

1000 feet (above sea level) - 2000 feet (final descent) = -1000 feet (below sea level).

In this scenario, the positive changes are the descents, but the final elevation is a negative number.
