Assuming spring constant for system A (left) is k
Then system B (middle) is k/2 and system C (right) is 2k

replace the two springs in parallel with the spring with the equivalent spring constant. Now you have two springs in series.

How about it? Do you have a question? Showing us pretty graphs doesn't tell anyone what you're stuck on. Also, those bold sentences are there for a reason: use them. State the question, give the relevant equations, and show your attempt at a solution, and then maybe I can give you a hint (or someone else can -- I'm a beginning physics student as well, so I make a lot of mistakes!).

Assuming you understand these statements, which describe the effect of adding springs in series or parallel, you can apply them directly to the new system. Hint: Start by replacing the bottom two springs by with an equivalent single spring.

Looks like rock.freak667 beat me too it!

Thanks. Solved it. =D
