※ 引述《htbk (小小艾佛森)》之銘言：
: 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
11thOG PS-139，答案B
範圍是39.05~40.825
more than 10 percent 即 >10%
less than 15 percent 即 <15%
如果要包含會用no less than 10%(不少於10%) 跟 no more than 15%(不多於15%)
這樣就可以等於了
