Answer:
-50.47
Step-by-step explanation:
So you see how there is a +(- ? That means to ignore the + and just subtract. BUT, when you subtract negatives it's simply adding them together.
So to do it you would say 37.27 + 13.2 which gives you 50.47. Then make it negative and boom there is your answer!
