For this case we have:
We evaluate each of the options given according to George's record:
A) The afternoon temperature was 5 degrees above the night temperature: The temperature at night was 0°F while in the afternoon it was +5°F. So, we subtract the temperatures:
Temperature in the afternoon - temperature in the night =
+ 5°F-0°F =+5°F, Thus, the temperature of the afternoon is +5°F above the temperature of the night
So, this statement is correct.
B) The afternoon temperature was 5 degrees above the morning temperature: The temperature in the morning was -2°F while in the afternoon it was +5°F. So, we subtract the temperatures:
Temperature in the afternoon - temperature in the morning =
+5°F-(-2)°F=+7°F, Thus, the evening temperature is +7°F above the morning temperature. So the given statement is not correct.
C) The morning temperature was 2 degrees above the afternoon temperature .: The temperature in the afternoon was +5°F while in the morning it was -2°F. So, we subtract the temperatures:
Temperature in the morning - temperature in the afternoon =
-2°F- (+5°F)=-7°F, so, the morning temperature is -7°F below the evening temperature. So the given statement is not correct.
D) The morning temperature was 2 degrees below the afternoon temperature.
The temperature in the afternoon was +5°F while in the morning it was -2°F. So, we subtract the temperatures:
Temperature in the morning - temperature in the afternoon =
-2°F-(+5°F)=-7°F, so, the morning temperature is -7° F below the evening temperature. So the given statement is not correct.
Answer:
The correct statement is: The afternoon temperature was 5 degrees above the night temperature.
