Answer:
cool.
Step-by-step explanation:
First off, because the temperature is decreasing, that means the final answer would be negative, or we can also say that there would be a -1 to be multiplied by the change.
Each hour temperature changes by 7. The question also says that temperature keeps on changing for 3 hours. Therefore the temperature change would be by 3 7's, or 7+7+7.
Lastly, add the -1 from the beginning since it is a negative temperature change, the answer is (-1)(7+7+7)
