Harness Racing ... Bet at your own risk.

I am confused here. It says there was a $600 3 horse exacta box played off shore on the top 3 finishers. Does mean that the ticket was a $100 exacta box for a total of $600 or was it s $600 exacta box for a total of $3,600? I mean $300 times $25.40 is $7,740.00. Pretty weird to fix a race for only $4140.00. It is the other it is it yileds a $1270 return. This doesnt seem right--lol.
