I've got a question to ask about the Nash Demand game from my assignment.
Sarah and Ruth find \$100 on the ground and decide to split it between them in the following manner. Each individual simultaneously and independently selects how much of the \$100 she wants to keep. Denote this value by . If +≤100, then each player receives the amount she desires. If +>100, they forfeit the \$100, and each player receives \$0. Find all of the Nash equilibria. Explain how you come to your conclusion (i.e. how you know that your answer is exhaustive.)
I'm quite lost as to how to even start the question. Thanks in advance to anyone! :)
