In City A, the temperature rises 4(degrees)F 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. Use pencil and paper. Which city has the greater change in temperature?

City A:

City B:

City B has a greater change in temperature.

Step-by-step explanation:

City A:

Let the initial temperature of city A at 8 AM =

Temperature change from 8 AM to 9 AM: 4 rise

Temperature at 9 AM =

Temperature change from 9 AM to 10 AM: 7 drop

Temperature at 9 AM =

Total change in temperature = drop

City B:

Let the initial temperature of city B at 8 AM =

Temperature change from 8 AM to 9 AM: 6 drop

Temperature at 9 AM =

Temperature change from 9 AM to 10 AM: 2 drop

Temperature at 9 AM =

Total change in temperature = drop

Therefore, the answer is:

City B has a greater change in temperature.
