7.5 degrees C to -5.21 degrees C. Kayla and Jason were discussing the changes in temperature. Kayla said, "Wow, I can't believe the temperature fell 12.71 degrees C." Jason said, "What are you talking about? The temperature only fell 2.29 degrees C." Who is correct

Kayla is correct. The temperature change TC is:
TC = High Temp - Low Temp
TC = 7.5 - (-5.21)
TC = 7.5 + 5.21 (Since a minus negative is positive)
TC = 12.71
