Final answer:
After a decrease of 2 degrees on Saturday from 82 degrees Fahrenheit, and an increase of 2 degrees on Sunday, the temperature on Sunday returned to 82 degrees Fahrenheit.
Explanation:
The temperature on Friday was 82 degrees Fahrenheit. On Saturday, the temperature changed by -2 degrees, bringing it down to 80 degrees Fahrenheit. Then, on Sunday, it changed by +2 degrees, which brought it back up to 82 degrees Fahrenheit, the same temperature as it was on Friday. To find the temperature on Sunday, we need to start with the initial temperature on Friday, which is given as 82 degrees Fahrenheit. We then have a temperature change of -2 degrees on Saturday, followed by a change of +2 degrees on Sunday.
So, starting from 82 degrees Fahrenheit, we subtract 2 degrees on Saturday, which gives us a temperature of 80 degrees Fahrenheit. Then we add 2 degrees on Sunday, which gives us a final temperature of 82 degrees Fahrenheit.
