问题：off少见的用法,whatisitandwhy?IfLucyal 
If Ly alters her selectionto 99, the outcome will be (99, 100), and she will earn$101. Because Lucy is better off by this change, the outcome(100, 100) is not a Nash equilibrium.
回答：这里off 是形容词，意思是“有某种东西(主要指money)数量的多少"。
常和well,badly,better等连用。

be well off: 有钱，富有；be badly off: 贫穷，没钱。由此派生的形容此有well-off,better-off,best-off,badly-off,worse-off,worst-off.意思不言自明。

Lucy would be better off choosing a number larger than 2. 如果选大于2的数，得的钱会更多。
