If there are 4 hearts on a card, a standard deck of 52 playing cards will have 208 hearts.
There are twice as many cows in Devonshire as there are hearts on a standard deck of 52 playing cards, meaning there are 2*208 = <<2*208=416>>416 cows in Devonshire.
The total cost of the cows when they are sold at $200 each is 416*$200 =$<<416*200=83200>>83200
#### 83200
