conversations.value: Can you walk me through the solution of: John's dog has a litter of 8 puppies.  He gives away half of them.  He keeps one of the remaining puppies.  He then takes the remaining puppies and sells them each for $600.  He had to give the owner of the stud $300.  How much money does he profit?

conversations.value: He had 8/2=4 left after giving some puppies away
  He then keeps one so he sells 4-1=3 puppies
  That means he made 3*600=$1800
  So his profit was 1800-300=$1500
