科目：个体经济学
写题目时遇到这题完全不知如何下手,所以想上来问问
Mary consumes tomatoes and nectarines. Mary's indifference curves are kinky.
When she is consuming more tomatoes than nectarines, she is just willing to
trade 3 tomatoes for 1 nectarine. When she is consuming more nectarines than
tomatoes, she is just willing to trade 4 nectarines for 1 tomato. Let p1 be
the price of nectarines, and p2 be the price of tomatoes. Mary maxmizes her
utility subject to her budget constraint. Draw three of her indifference
curves. Under what condition will she consume only tomatoes?
我觉得我的问题好像是出在＂she is willing to trade ... for ..."这两句上
不太懂他的文意，原本的解读是在那个情况下，购买番茄/桃子数的比例
但想画无异曲线却没什么头绪......
想麻烦大家给点提示或想法QQ 谢谢!!
