Okay, so I went out on a limb and made the parlay below based on a random hunch that these two results would come through... without much basis, I just sort of woke up and said, "yea, I think the Gunners and Spurs are gonna win." If I made an initial stake of $40 which would pay out about $355 I believe, how much should I separately put on the DRAW (at +215) and MAN U to win (at +165) now to hedge my initial bet for at least some profit?
PARLAY (2 TEAMS)
ARSENAL +235 WIN
TOTTENHAM +165 PENDING
Thanks for your suggestions!
