From May 1 to May 30 in the same year, the balance in a checking account increased. What was the balance in the checking account on May 30?

(1)  If, during this period of time, the increase in the balance in the checking account had been 12 percent, then the balance in the account on May 30 would have been $504

(2)  During this period of time, the increase in the balance in the checking account was 8 percent.          Answer=A

我选的是C，恳请大家帮忙解答，谢谢

条件2，只是说这一个月增加了8，但是没有1号的数据就不能算出30号啊，所以条件2单独不充分

而条件1已经回答问题了，直接选A就可以。

答案错，C
