The local meteorologist claims that the temperature is going to steadily drop over the next 4 hours. If the temperature changes by the same amount each hour, and it changes by a total of -28°F, how much will it change each hour? Explain how you got your answer in two or more complete sentences.
The answer is -7 degrees per hour because if it changes the same over 4 hours, and changes -28 degrees in total, you can divide the two (-28/4), and you will get -7 degrees per hour.
