-47°F (option A)
Step-by-step explanation:The temperature in the late afternoon = -23.5°F
The temperature dropped by 11°
A drop in temperature means a negative temperature
It becomes: - 11°
It dropped by 12.5° = -12.5°
The temperature at midnight = -23.5°F + (-11°F) + (-12.5°F)
= -23.5°F -11°F - 12.5°F
The temperature at midnight = -47°F (option A)
