simple question on implied odds and effective odds

[wrto4556]

not sure if this goes in this forum or not. Im not really questioning whether the hand was played right or not, but more if im calculating my effective and implied odds correctly.

5/10 (3 handed)

I have 5 [img]/images/graemlins/diamond.gif[/img],2 [img]/images/graemlins/diamond.gif[/img] in the SB.
button limps, I complete, BB checks.

flop is J [img]/images/graemlins/heart.gif[/img],5 [img]/images/graemlins/heart.gif[/img],7 [img]/images/graemlins/diamond.gif[/img] (3sb)
I bet, BB calls, Button calls.

turn is the 8 [img]/images/graemlins/diamond.gif[/img] (3BB)
I check, BB bets, Button raises...

Is this call profitable?

Assuming it gets capped behind me and both players are in, all I need to do is make up 1.25BB on the river, correct?

i'd be getting 11-4 or 2.75-1...I need 4-1.

This is an easy call, right?
