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.

Anthony starts his dive in a boat 6 feet above sea level. He descends to see a shipwreck 234 feet below sea level.

Answer 1

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

Anthony starts his dive in a boat 6 feet above sea level. He descends to see a shipwreck 234 feet below sea level.

In this case, the change (the action of descending) can be seen as a positive number (+234 feet), but the end result, being below sea level, is modeled by a negative number (-234 feet).

Answer 2

are you sure

Answer 3

Let me clarify the reasoning for the scenarios provided:

1. Irene is scuba diving 20 feet below sea level. Her sister tells her to swim 5 feet up towards the surface to see a school of fish.

   • Change: +5 feet (she swims up)
   • End result: 20 - 5 = 15 feet below sea level (still negative)

2. David is flying a plane at 2,350 feet. He then ascends 1,200 feet to avoid a storm cloud.

   • Change: +1,200 feet (he ascends)
   • End result: 2,350 + 1,200 = 3,550 feet (positive)

3. 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.

   • Change: +130 feet (she ascends)
   • End result: 130 - 130 = 0 feet (ground level, neither positive nor negative)

4. Anthony starts his dive in a boat 6 feet above sea level. He descends to see a shipwreck 234 feet below sea level.

   • Change: +234 feet (he descends)
   • End result: 6 - 234 = -228 feet (negative)

In terms of the original question, the scenario that fits the criteria of a change modeled by a positive number, but an end result modeled by a negative number is Irene’s or Anthony’s scenario.

Upon reevaluation, Irene's scenario actually does fit the criteria more neatly since while she swims up, she still ends up at a negative value, whereas Anthony starts higher (above sea level) and ends lower in a more strict definition of above and below.

I appreciate your patience, and I confirmed: Irene's scenario is appropriate given the terminology as it both involves a change (upward movement) leading to a negative outcome. Thank you for allowing me to reevaluate my response!
