Answer:
\(45^{\circ}F\)
Step-by-step explanation:
We have been given that one winter day,the temperature ranged from a high 20°F to a low -25°F.
To find the degrees by which temperature dropped, we will find difference between the final temperature and initial temperature.
\(-25^{\circ}F-20^{\circ}F=-45^{\circ}F\)
Since our difference is negative, therefore, the temperature dropped 45 degrees Fahrenheit.
