During a winter's night, the low temperature was recorded at 19°F. The wind-chill temperature that same night was -7°F. What was the difference between the wind-chill temperature and the low temperature?

f 7°F g 12°F h 25°F j 26°F

The difference between the wind-chill temperature and the low temperature was 26°F.

To find the difference, you simply subtract the low temperature from the wind-chill temperature:

-7°F - 19°F = -26°F

However, since the question asks for the difference as a positive value, you would take the absolute value of -26°F, which is 26°F. Therefore, the answer is j) 26°F.
