问题如下：
1. In 2007, the company’s net income (loss) was closest to:
选项：
A. ($217,000).
B. ($329,000).
C. ($556,000).
解释：
C is correct.
The income tax provision at the statutory rate of 34 percent is a benefit of $112,000, suggesting that the pre-tax income was a loss of $112,000/0.34 = ($329,412). The income tax provision was $227,000. ($329,412) − $227,000 = ($556,412).
解析：
federal tax expense( benefit)=pre-tax income* federal tax rate
已知federal tax expense和federal tax rate，那么我们就可以反求出pre-tax income (loss) 是($329,412)。
又因为 net income=pre-tax income-income tax expense
已经求出pre-tax income (loss)，又已知income tax expense是 $227,000，则可求得Net income (loss) = ($329,412) - $227,000 = ($556,412)
income tax expense和expected federal income tax expense为什么不是一个东西？这两个不都是企业自己算出的税额吗？哪个是实际交的税？
