(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.

答案是D,我觉得这个好像不对,应该选C嘛，大家看看咧

我也錯了這題

4.40 = 0.29 * 10 + 0.15 * 10

所以各買10張

只能這個組合 所以 滿足~
