Final answer:
To find the midnight temperature, subtract the temperature drop (36°F) from the 6:00 p.m. temperature (24°F), resulting in -12°F.
Step-by-step explanation:
The student asked about the temperature change from 6:00 p.m. to midnight. To find the temperature at midnight, we start with the temperature at 6:00 p.m., which was 24°F. Since the temperature dropped by 36°F at midnight, we subtract 36 from 24:
24°F - 36°F = -12°F
Therefore, the temperature at midnight was -12°F, which corresponds to option B in the question.
