[問題]GMATPrep PP 01-25

[shine822]

我要問的問題是最新 GMATPOWERPREP程式 裡面的問題
但我因為沒啥人有OG11th 所以暫時無法對照題號甚至不清楚是否有重複
請見諒!!

我已想盡辦法 新發明比較好辨認的題號了
當然版主大大若有更好的同一格式
請隨意修改標題 感激不盡

Q25.
PS: A certain library assesses fines for overdue books as follows. On the first day that a book is overdue, the total fine is $0.1. For each additional day that the book is overdue, the total fine is increased by $0.3 or doubled, whichever is fined lesser. What is the total fine for a book on the fourth day it is overdue?

A. 0.6
B. 0.7
C. 0.8
D. 0.9
E. 1.0

Ans. B


就我的理解
我計算的表格如下
Overdue: 1st----2nd----3rd----4th
Fine_____0.1___0.4___0.7___1.0 ...(+0.3)
________0.1___0.2___0.4___0.8...(doubled)
因為 0.8<1.0 取較少金額來罰款
第四天不是應該罰C元嗎

不知哪裡理解錯誤了耶
請賜教
感激不盡啦~~

小弟猜想您應該是對上面紅色那句話誤解了, 那句話的意思應該如下:
1st : $0.1
2nd: min{0.1+0.3, 0.1*2} = 0.2
3rd: min{0.2+0.3, 0.2*2} = 0.4
4th: min{0.4+0.3, 0.4*2} = 0.7
所以答案是(B)
