The real-world problem that could be solved with the sum \(−22 + 9\) is: The temperature was −22°F yesterday. Today the temperature is 9°F. How much warmer is it today compared with yesterday?
This scenario clearly illustrates the concept of calculating the difference in temperature between two days, resulting in a positive change in temperature.

The correct response that could be solved with the sum \(−22 + 9\) is: 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 effectively deals with point totals that could be negative and involves adding a positive value to it, which aligns with the mathematical expression \(−22 + 9\).
Question Solve the following problem: It was −8° F this morning, but the temperature has gone up 11° over the course of the day. What is the temperature now?(1 point) Responses 3°F 3 degrees F −3°F negative 3 degrees F 19°F 19 degrees F 11°F
To solve the problem, you start with the initial temperature and add the increase in temperature:
\[ -8°F + 11°F = 3°F \]
So the temperature now is 3°F (or 3 degrees F).
Question There are some areas of land on Earth that are below sea level. Imagine you are at the Dead Sea in Africa, which has an elevation of about −1,410 feet (1,410 feet below sea level). You then climb up 125 feet. What is your new elevation?(1 point) Responses −1,535 feet negative 1,535 feet 1,285 feet 1,285 feet −1,285 feet negative 1,285 feet −1,335 feet negative 1,335 feet
To find your new elevation after climbing up 125 feet from an elevation of \(-1,410\) feet, you can add the height climbed to the elevation:
\[ -1,410 + 125 = -1,285 \]
Therefore, your new elevation is −1,285 feet (or negative 1,285 feet).
Question Reem owes her friend $15.25. Reem works after school and earns $43.78. After paying her friend back, how much money does she have?(1 point) Responses −$59.03 negative $59.03 dollars −$28.53 negative $28.53 dollars $28.53 $28.53 $59.03
To find out how much money Reem has after paying her friend back, you can first calculate how much money she has left after repaying the debt. Here’s the calculation:
- Start with her earnings: $43.78
- Subtract the amount she owes her friend: $15.25
\[ 43.78 - 15.25 = 28.53 \]
Therefore, after paying her friend back, Reem has $28.53.
