Really simple questions

[Mr. Pozzer]

Jay, thank you for all that math. I'm still trying to digest all of it so I can put it to use in future hands. Can you explain something to me though, please?

If (.31)*($25.75(pot after I call)) = $7.98 it would seem to a math novice like me that only a call of $7.98 (11.48 total) would make me break even since this is my equity if I call. Can you tell me why this is wrong please. I'm not doubting your answer at all I'm just trying to figure all this out.

Does the above equation also say that I'm making $.98 if I call the $7 raise if the hand ends now?
