Answer:
D
Explanation:
We want to find the difference between -0.4 and 44.4: 44.4 - (-0.4).
Remember that when we have two negative signs next to each other, they cancel each other out and become positive. In this case, the two negatives become positive, so we're left with: 44.4 + 0.4 = 44.8
The answer is D.
Hope this helps!
