from 5 am to 10 am is 5 hours.

The temperature rose 5 degrees per hour.

Multiply the rise per hour by the number of hours:

5 x 5 = 25 degrees.


Now add that amount to the original temperature:

-20.5 + 25 = 4.5 degrees.


The answer is:

C. Melissa added incorrectly. The correct answer is 4.5°F
