Answer:
74.4°F?
Explanation:
It started at 65°F and they recorded the change. So 65 + 2.5 = 67.5 - 1.7 = 65.8 + 5.5 = 71.3 + 3.1 + 74.4? I think that is how it is solved. I could be wrong... it's been a while haha
^^That is finding the full temp. overall. If you are looking for the change, it is 9.4
