As a 'proposer': Decide how much you would 'propose' splitting $X between yourself and another participant. Remember the other participant (the 'responder') has the power to reject your offer. Use only integer numbers in your proposals, i.e. round dollars and not cents.

As a 'responder': Decide whether to accept or reject the amount of money you have been offered out of the total $X by the 'proposer'. If you accept the offer you each keep the proposed amounts, if you reject the offer you both get nothing.

As a proposer (Remember that the responder can reject your offer) If I had to split $10,000, I would propose ___________ to myself, and the rest to the responder. (please fill in the blank)
