The Blue devils had won 37.5 games. they had played 24 games altogether. how may games had they won?
lubasha [3.4K]

The Blue Devils are trying to sell us a bridge and a bill of goods.
But we are sharp, and we are not falling for their story.

We are smart enough to spot two glaring weaknesses in their story.

1).  There is no way to win  .5  of a game.

2).  There is no way to win 37 games if you've
only played 24 so far.
