Step-by-step explanation:
The expression that can be used to find the temperature in the morning is B. 22-(-31).
In the given scenario, the temperature outside was 22 degrees Fahrenheit and it dropped 31 degrees Fahrenheit overnight. To find the temperature in the morning, we subtract the change in temperature from the initial temperature. Here, 31 degrees Fahrenheit is subtracted from 22 degrees Fahrenheit.
22-(-31) = 22 + 31 = 53 degrees Fahrenheit
