"Two springs are hooked together and one end is attached to a ceiling. Spring A has a spring constant of 25N/m, and spring B has a spring constant of 60N/m. A mass weighing 40.0N is attached to the free end of the spring system to pull it downward from the ceiling. What is the total displacement of the mass?" (-2.3m)

Each has 40N pulling on it. x=F/k solve for each x (displacement). Add them to get total displacement. Yes, and at the ceiling the force is 40 N.
