How much would he have won, if the Broncos had won?

[Enterprise]

If he wanted to win 10,400,000 he would have to put up the 10,400,000 plus a 1,040,000 bookie fee. If he won the bet he would win 10,400,000 and get the bookie fee back. If he lost the bet he loses the 10,400,000 plus the 1,040,000 for a loss of 11,440.000.

However if he put the money up and said that's what he wanted to bet, then he would be putting up 10,400,000 to win 9,360,000. A win gets him 9,360,000 plus getting the 1,040,000 bookie fee back. A loss means he loses 10,400,000.
