Final answer:

After starting at -6°F at 5:00 a.m., the temperature rose by 15°F by noon, leading to 9°F. It then dropped by 5°F by 7:00 p.m., resulting in a final temperature of 4°F.

Step-by-step explanation:

The question involves calculating the final temperature after several changes. To solve it, we start with the initial temperature and apply the changes sequentially.

At 5:00 a.m., the temperature was 6°F below zero. By noon, it rose by 15°F, so we add 15 to -6:

-6°F + 15°F = 9°F

At 7:00 p.m., the temperature dropped by 5°F from the temperature at noon:

9°F - 5°F = 4°F

Therefore, the final temperature at 7:00 p.m. was 4°F.

The answer to the question is B. 4°F.
