In City A, the temperature rises 4F from 8 A. M. To 9 A. M. Then the temperature drops 7F from 9 A. M. To 10 A. M. In City B, the temperature drops 6F from 8 A. M. To 9 A. M. Then the temperature drops 2F from 9 A. M. To 10 A. M. Write an expression that represents the change in temperature from 8 A. M. To 10 A. M. For each city. Simplify and interpret each sum.
