this varies depending on opponents and stack sizes. we've used 12X, David used a higher number, doesn't really matter save for you need to expect at least 12X your preflop investment for it to be profitable. in the example you have the sunk cost of $35 so you would call the $75 raise if you could EXPECT to make $900-$1175 when you hit a set or better AND WIN. you suck up the loss of $35 because that's dead money once you get to the reraise.

the more conservative numbers allow for deeper stacks and more flush and straight hands played among other things. we worked around 100bb in a tightish game.

and, if getting reraised happens a fair amount of the time you should reevaluate your preflop raise, or at least the size of it when you play a range that consists mainly of pairs.
