Q35:

The total charge to rent a car for one day from Company J consists of a fixed charge of $15.00 plus a charge of $0.20 per mile driven. The total charge to rent a car for one day from Company K consists of a fixed charge of $20.00 plus a charge of $0.10 per mile driven. Is the total charge to rent a car from Company J for one day and drive it x miles less than $25.00 ?

(1) The total charge to rent a car from Company K for one day and drive it x miles is less than $25.00.

(2) x < 50

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.

答案为D, 我觉得选A

条件B: 15+0.2x<35, 不能确定是否<25啊？

我不是很懂妳最後一句的意思,應該是"不能确定是否<25啊"...是嗎?

題目的條件
company J total charge = 15+0.2x
company K total charge = 20+0.1x

題目問
是否company J total charge < 25

條件(2) >> x<50 >> 代回
company J total charge = 15+0.2x < 25
故條件(2)成立

你應該是有計算錯誤,請驗算看看....參考..

太慌张了！15+0.2*50竟然算成了35

考试时候一定注意！快考了，天天赶着做题，总出现这种慌张问题

谢谢
