Morning temperature = −2°F Afternoon temperature = +5°F
Night temperature = 0°F

Which statement is correct, based on the given temperatures?

The afternoon temperature was 5 degrees above the night temperature.
The afternoon temperature was 5 degrees above the morning temperature.

i know the 2 below are incorrect, i have chosen A but i want to make sure i am correct.
The morning temperature was 2 degrees above the afternoon temperature. Χ
The morning temperature was 2 degrees below the afternoon temperature. Χ

You are correct it would be A.

From night (0) to afternoon (5) is 5 degrees higher.

Option B is asking about from morning to afternoon. So from -2 to 5. First we have to bring the negative number to 0, you have to add 2 to -2 to get zero. Then we have to go more positive until we get to 5, which is 5 more. So from -2 to 5 we had to move a total of 7. Option B says we only moved 5 degrees, which we can see in untrue since it was 7 degrees above.

Hope that helps! If your still confused take a look at a number line, and feel free to comment with any questions!
