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 uses the concept of temperature, where -22 represents a temperature below freezing, and a positive temperature of 9°F indicates a warmer day. The calculation can determine the difference in temperature.
While the other options also involve scenarios that can be solved with addition and subtraction of positive and negative numbers, the temperature comparison is the clearest representation of the situation described by the equation -22 + 9.
