(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.

The first condition gives you the initial amount on May 1st: 504/1.12
The second condition gives you the way to calculate the amount on May 30 if you know the amount on May 1st. [$$ on May 1st]*1.08

Choose C.

美国银行中
Checking: 活期，利率低，近乎没有。但是存取自由。有的时候有手续费用

Saving:存款账户，利率还是低，刺激存款的一种便利方式

CD: 死期，利率稍高。定期。跟国内的规定很像。

废话点背景而已。呵呵。明天就考，有点紧张。
