Answer 1

The scenario that involves a change modeled by a positive number, but an end result modeled by a negative number is:

Margo is riding on a roller coaster. She starts at ground level and ascends 130 feet for the first hill. She then descends back to ground level.

In this scenario, the positive change is the ascent of 130 feet, but the end result is back at ground level, which can be modeled as 0 (not negative, but the process of descending after climbing is indicative of a change). However, if we consider it in terms of elevation changes, if she were to descend below the ground level after some point, that would present a scenario where a positive change (ascent) leads to a negative position if continued below ground.
