Problem
The temperature in Middlefield at 6 A.M. was -15°F. By 3 P.M., the temperature had risen 19°F. What was the temperature at 3 P.M.?
Solution
For this case the initial temperature at 6 A.M was -15 F and we know that by 3PM the temperature rise 19F so we can do this to find the final temperature:
T = -15 +19 °F= 4°F
And we can conclude that at 3pm the temperature would be 4°F
