C

Step-by-step explanation:

First of all -2-5= -7

It isn't (A) because (A) is saying that the beginning temperature was a postive number, which it wasn't The beginning temperature is -2, which is negative. So we can cross that off.

It isn't (B) because (B) is saying that you start off with -2 and then it gets warmer, and temperature adds up onto it. When you do -2 +5, you get 3, which is not the answer.

So, the answer is c

Proof: It starts of with negative 2, which is the first temperature. Then, it says decreased by 5, which is what is happening. 5 is getting subtracted from -2

So, the answer is C
