The temperature outside dropped 13°F in 7 hours. The final

temperature was - 2°F. What was the starting temperature?

11

Step-by-step explanation: Since the question does not specify wether the temperature dropped every hour or if it was the total, in this case we can assume this was in total. If you ended up with - 2 after subtracting 13, to get the starting temperature you can add - 2 to 13.

-2 + 13 = 11
