Use the order of operations to find the value of the given expression:


(-125+175)+(-125+165)+110

Solve the expression inside the parenthesis first.

Since -125+175=50 and -125+165=40, then:


(-125+175)+(-125+165)+110=50+40+110

Add the numbers from left to right:


50+40+110=90+110=200

Then:


(-125+175)+(-125+165)+110=200

Therefore, the answer is:


C\text{. }200
