Final answer:
The current temperature is -9°F.
Step-by-step explanation:
The temperature at 6 AM was -5°F. At 9 AM, the temperature had risen by 8°F. At 4 PM, the temperature dropped another 12°F.
To find the current temperature after the drop at 4 PM, we need to subtract 12°F from the temperature at 9 AM. The temperature at 9 AM was -5°F + 8°F = 3°F. Subtracting 12°F from 3°F gives us -9°F as the current temperature after the drop at 4 PM.
