A city’s record high temperature is 103 degrees, and the record low is -15 degrees. How much warmer is the record high than the record low?

To find out how much warmer the record high temperature is than the record low temperature, you can subtract the record low from the record high:

1. Record high temperature: 103 degrees
2. Record low temperature: -15 degrees

Now, perform the subtraction:

\[ 103 - (-15) = 103 + 15 = 118 \]

So, the record high temperature is 118 degrees warmer than the record low temperature.
