The sum −22 + 9 can apply to several real-world contexts, but the most fitting scenarios would be the first two options regarding points in a card game and temperatures.
-
Quinn is playing a card game with his friends. He had −22 points at the start of his turn, but just got 9 points. How many points does he now have?
- This scenario represents a situation where Quinn starts with a negative score and gains points, making it a direct application of the sum −22 + 9.
-
The temperature was −22°F yesterday. Today the temperature is 9°F. How much warmer is it today compared with yesterday?
- This scenario appropriately uses the sum to find the difference in temperature, reflecting the change in temperature from a negative value to a positive one, again aligning with the calculation of −22 + 9.
Both of these options involve the use of the sum in a practical manner, but since they represent different contexts, the first is about scoring in a game, while the second is about temperature change.
The last two scenarios (about the scuba diver and Layla earning money) involve different arithmetic and aren't directly represented by the equation −22 + 9.
In summary, either of the first two options would be correct, but if we need to choose one, the card game example provides a clear and relatable context for the sum's application in a straightforward manner.
