To determine which situation results in a final value of zero, let's analyze each option:
A. The temperature after an increase of 7° C from a temperature of –7° C:
- Starting temperature: –7° C
- After increase: –7° C + 7° C = 0° C (This results in zero.)
B. A video game score of 500 points for round 1 and 500 points for round 2:
- Total score: 500 + 500 = 1000 points (This does not result in zero.)
C. The distance above sea level after increasing 32 feet from a depth of 32 feet:
- Starting depth: –32 feet (below sea level)
- After increase: –32 + 32 = 0 feet (This results in zero.)
D. The amount of money Charlotte had if she had $12 and then her mom gave her $12:
- Total amount: 12 + 12 = $24 (This does not result in zero.)
Both A and C result in a final value of zero. However, if you must choose just one, option C provides a clearer situation of returning to sea level (zero feet).
So the best answer is C: The distance above sea level after increasing 32 feet from a depth of 32 feet above sea level.
