In the explanation

Step-by-step explanation:

So we are looking at the total profit of wagging tails.

in 2010, they earned -400.

in 2011, they earned -200.

in 2012, they earned 200.

so if you add negatives, they are still negatives.

-400+(-200)=-600.

But they also made a profit of 200 in 2012, so you would add that to the sum as well.

add the negative to the positive

-600+200. This decreases the negative number and brings it closer to 0 or any other positive number.

the sum is -400.

Hence, the answer will be -400.
