Captain Cooks 35X WR

[Burno]

Since the casino's have cut down on our whoring I am a bit leery about giving it another go. Cap'n Cook's has a 200 for 100 offer, available in pounds, but with a 35WR. They do offer Vegas Strip Blackjack, $1 bets, and autoplay. Could someone please walk my ignorant ass through the math required to calculate the EV and ROR for this?

35 X 300 is 10500. And after this I'm stumped. [img]/images/graemlins/smirk.gif[/img]

And sorry if this should be in the probability forum, I just figured more whores hang out here.
