Dunbar/All: Parlay Question

[Scav]

So Sunday at Toga I was forced to play the late pick four when I really wanted to play a pick three starting in race 7. I just realized after I am mentally going over the whole weekend that I could have played a win parlay which is essentially a pick three. That being said, the prices of my horses were $9, $16.80, $2.70. If I wanted to play a ticket that was 2x3x2, the parlay would have cost $12 correct? and I would have gotten back $51.03 per $1??

I don't have the opportunity of parlays at Arlington so this was the first experience with them. Given that a pick three wasn't offered, this would have been a decent substitute, I wish I would have thought of it because I got knocked out of the final leg of the pick four....I played the pick four three times at $24 so I would have had the above win parlay 6-10 times if I could have played it.

Let me know if this math was correct.
