Big enough edge to take?

[a nonymous]

Could anyone help me work through the process of figuring out whether or not an edge (a chip-equity edge) is big enough to take in a turbo sit&go? I already have the exact numbers for the problem, I just don't know how to "solve" it. I am more interested in the process of solving this type of problem than the answer to this specific problem. I am totally new to this and any advice would really help me out.

Blinds at 50/100. Player limps, player minraises, action is on hero. Hero has 1275. Hero is not in the blinds. Hero has two options:

A) Push and get called by minraiser who has him covered, everyone else folds. (So total pot 2800.) Hero's equity is 53.3%.

B) Fold.

9.09% rake for the sit&go. 3 places paid (9 players left, let me know if you need all of the stack sizes). Hero has a 10% ROI through a significant sample. Let me know if there's anything I'm leaving out/anything else that needs to be considered.

Thanks a lot.
