An agent comes to a Player with a business proposition. For a $30,000 investment, the agent can return $60,000 by the end of the year. If the Player can invest $50,000, the agent can return $115,000. In both cases, the Player wants his money plus 50%. Assuming the Agent has the option of actually doing the work or running with the investment money, should the Player A) pass on the opportunity, B) invest $30,000, or C) invest $50,000?

If the Agent were to require collateral, how much would he need to justify any investment not already agreed upon?
