Answer:
The Correct Answer is option D.
Step-by-step explanation:
Tina observed that the temperature was 72 degrees. Later the temperature rose 21 degrees and then dropped 11 degrees.
That is, 72+21-11=82.
She then flew to New York where the temperature was 67 degrees.
The change in temperature from when Tina left Atlanta and arrived in New York is,
82-67=15.
Hence, the change in temperature is 15.
Thus, the correct option is D.
