In order to solve this you need to find the difference in temperatures at 2 different times which in other words is how many degrees more or less has changed from starting to temp to the end temp
So the starting temperature was 80 degrees and the final temperature was 97 degrees. So all you need to do is 97-80 which gives us the difference in temperatures.
So the answer would be 17 degrees because that is the difference between are values.
