A city’s record high temperature is 106°F

To find out how much warmer the city's record high temperature is than the record low temperature, you can use the following calculation:

1. Record high temperature: 106°F
2. Record low temperature: -17°F

To find the difference, you subtract the record low from the record high:

\[
106°F - (-17°F) = 106°F + 17°F = 123°F
\]

Therefore, the city’s record high temperature is **123°F** warmer than the record low temperature.

The correct response is:
**123°F**
