To find out how much warmer the city's record high temperature is than the record low temperature, you can subtract the record low temperature from the record high temperature.
Record high temperature: 106°F
Record low temperature: -17°F
So the calculation is:
106°F - (-17°F) = 106°F + 17°F = 123°F
The record high temperature is 123°F warmer than the record low temperature.
The correct response is: 123°F.
