GWD01 Math30 请教+征个G友

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.

答案是D,我选的是A，百思不得其解啊，郁闷，查了以前的讨论没有这道题

顺便征个G友，我打算12月考，在职复习，现在基本上各个部分都熟悉了，阅读和写作还需要强化一些就可以模拟套题了；自己一个人复习太郁闷了，找不到人 一起讨论。msn：barila.bai(A) hotmail.com

AGREE. THE ANSWER IS A.
