Lets Get this Blog out of the Muck

I was at park's game and was sitting at about 300$. i bought in for 2 so i was up about 100. I have the button and i pick up jacks. A girl, who had been playing very tight raises to 15. There is one caller before me and then i call and everyone else folds. The flops comes A J 4 rainbow. She leads out for 30, next guy folds, actions to me....what is the right play? (She has almost the exact amount of chips as i do give or take 10$$)
