In a small town, a bookstore received a shipment of books. The shipment included 150 mystery novels, 120 science fiction books, and 80 biographies. The bookstore decided to offer a discount where they sell mystery novels at $8 each, science fiction books at $10 each, and biographies at $6 each. If the bookstore sells all of the mystery novels and half of the science fiction books, how much total revenue will they generate from these sales?
