conversations.value: This math problem has got me stumped: Bob bought 2 show dogs for $250.00 each to breed as a side business.  The female just had a litter of 6 puppies.  If he sells each puppy for $350.00, what is his total profit?
  Can you show me the way?

conversations.value: He bought 2 dogs for $250.00 each so they costs 2*250 = $500.00
  He sells each of the 6 puppies for $350.00 so he'll make 6*350 = $2,100.00
  He made $2,100 on the puppies but spent $500.00 to buy the dogs so his total profit is 2,100-500 = $1,600.00
