Let's analyze each situation to determine which one results in a final value of zero.
A. The temperature after an increase of 7° C from a temperature of –7° C:
- Starting temperature: –7° C
- Increase: +7° C
- Final temperature: –7 + 7 = 0° C (This results in zero).
B. A video game score of 500 points for round 1 and 500 points for round 2:
- Round 1 score: 500 points
- Round 2 score: 500 points
- Final 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)
- Increase: +32 feet
- Final position: –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:
- Starting amount: $12
- Given amount: +$12
- Final amount: 12 + 12 = $24 (This does not result in zero).
Based on this evaluation, the situations that result in a final value of zero are:
- A: The temperature after an increase of 7° C from –7° C.
- C: The distance above sea level after increasing 32 feet from a depth of 32 feet.
Both A and C result in a final value of zero.
