才开始做第一套，整整花了我两个晚上，37道题都没做完。。。
感觉好难啊。

在这里问一个：
Q30:

Joanna bought only $0.15 stamps and $0.29 stamps.How many $0.15 stamps did she buy?

(1)She bought $4.40 worth of stamps.

(2)She bought an equal number of $0.15 stamps and $0.29 stamps.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.
为啥答案选D呢？我觉得是A。。。
