標題[問題] 一題簡單的數學觀念問題
時間Thu Mar 26 14:18:34 2009
A restaurant meal cost $35.50 and there was no
tax. If the tip was more than 10 percent but less
than 15 percent of the cost of the meal, then the
total amount paid must have between
(A) $40 and $42
(B) $39 and $41
(C) $38 and $40
(D) $37 and $39
(E) $36 and $37
題目中的 "more than 和 less than"是有包括 10% 和 15% 嗎?
那如果用哪個英文用字表達就不包含10% 和 15%了?
雖然這是滿簡單的一道題目，不過我還是想把觀念釐清
所以PO上來問一下
