lyse is correct. you have to call 113 and stand to win 113 + 176 = 289
thats 289:113 or 2.56:1 (28% equity)
If you find yourself getting tripped up on these things, just benchmark against some known facts.
1) if there is no pot then you need 50% equity to call a bet (because you need to be at least flipping a coin)
2) if you are facing a 1PSB, then you stand to win 2x Pot and it costs 1x the pot to call. So for every 3 times you call, you can win once and lose twice to break-even. so you only need to win 1/3 of the time (33%).
3) facing 1/2 PSB you stand to win 1.5x pot and it costs .5x pot. So for every 4 times you can lose 3x and win 1x to break even. So you only need to win 1/4 of the time (25%).
when you win, it doesn't cost you the bet. this is why the formula is bet / (bet + pot). it doesn't have to do with more betting to come.
