suppose that bridget and erin spend their incomes on two goods ,food(F) and clothing(C),bridget's preferences are represented by the utility function U(F,C)=10FC, while erin's preferences are represented by the utility function U(F,C)=20FC
A:with food on the horizontal axis and cloothing on the vertical axis , identify on a grph the set of points that give bridget the same level of utility as the bundle(10,5),DO the same for erin on aseparate graph.
主要翻译的A问题,后面的证明要求,特别是bundle(10,5)这个完全看不懂.....
那identify the set of bundles that give bridge and erin the same level of utility as the bundle (15,8)呢?
追答identify the set of bundles that give bridge and erin the same level of utility as the bundle (15,8)
确定消费束(消费组合)的集合,那些消费束能给bridge和erin带来与消费束(15,8)带来的相同的效用
