※ 引述《cindy2015 ()》之銘言： : Q. In the years following an eight-cent increase in the federal tax on a pack : of cigarettes, sales of cigarettes fell ten percent. In contrast, in the : year prior to the tax increase, sales had fallen one percent. : The volume of cigarette sales is therefore strongly related to the : after-tax price of a pack of cigarettes. tax increase P1 + T1 -----> P2 + T2 = P2 + T1 + 8 cent ^^^^^^^^^^^^^^^^ after-tax price 結果得到 sales 下滑 1% 題目歸因於 "after-tax price" 意思就是 after-tax price ↑ --> sales ↓ 問題是題目只說 tax incrase by 8 cents assumption 橋段產生: tax incrase by 8 cents --> after-tax price ↑ P1 + T1 < P2 + T1 + 8 cent P2 不能少於 P1 達到 8 cent 造成 after tax price 下滑 after tax price 下滑就不能說 sales 下滑是此原因 : The argument above requires which of the following assumptions? : A. During the year following the tax increase, the pretax price of a pack of : cigarettes did not increase by as much as it had during the year prior to : the tax increase. : B. The one percent fall in cigarette sales in the year prior to tax increases : was due to a smaller tax increase. : C. The pretax price of a pack of cigarettes gradually decreased throughout the : year before and the year after the tax increase. : D. For the year following the tax increase, the pretax price of a pack of : cigarettes was not eight or more cents lower than it had been the previous : year. : E. As the after-tax price of a pack of cigarettes rises, the pretax price also : rises. : 答案是D : 卻是看不明白怎麼推出的假設@@ : 是根據什麼咧? : 還請板友幫忙解答 : 謝謝 -- GMAT、各金融證照資訊交流 - 勇闖夢想的新鮮人 http://ndxica.pixnet.net/blog -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 111.248.211.11
