[問題] 猴哥第89,88,78題
題號跟前面的發問者都不太一樣
如果89題需要完整題目我再補上
89題
Rack A holds 80 pairs of....這一題
我把A最大的獲利可能 15*80 減去B的最大的獲利可能13*60
得到的答案是420
不過答案卻是413
所以題目是故要設計成要選最接近且有可能發生的選項嗎
88題
題目的英文看不懂
T is no more than 20 percent greater than the interger x, and 7 is no
smaller than a number 20 persent less than the integer x . If T=60,
which of the following indicates the smallest possible interval for x?
第一句的Than有點多 該怎麼翻譯題意會比較好?
78題
At a sales , the cost of each tie was reduced by 20 percent
and the cost of belt was reduced by 30 percent.
A. The percent reduction on the total cost of 1 tie and 2 belts.
B. 25%
這一題答案是不能比
我第六感也是不能比啦 但請問該怎麼證明....
