The city of Workney, in raising bus fares from $1.00 to $1.25, proposed that 18 fare tokens be sold for $20.00 to alleviate the extra burden of the fare increase on the city's low-income residents. Critics suggested alternatively that 9 fare tokens be sold for $10.00, because a $20.00 outlay would be prohibitive for low-income riders.
The alternative proposal depends on which of the following assumptions?

数学 JJ已经很全了
但有一道题,我不知道JJ有没有出现过,因为我只看到JJ的第300题…… 题目是这样的 a and x are both real numbers. -a<X<a² , is X positive ? 条件1:a²-a>0 条件2:a²+a<0 (条件1算出来a>1 or a<0,不充分,条件2算出来-1<a<0,但这样的话,就会变成-a>a²了,那X就不存在了,楼主就不知道这种情况到底是充分还是不充分……题目楼主肯定没有记错,但就不知道中间到底是哪个想法出错了……)
