16 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. 答案是A
我怎么觉得应该是C, （1）中条件,是虚拟语态，假设条件，只能推出May 1的balance,没有increase percent, 如何得出May 30 balance 请教大家了 |
