這題也是我在做PP的時候碰到的題目 Before being simplified, the instructions of computing income tax in Country R were to add 2 percent of one’s annual income to the average(arithmetic mean) of 100 units of Country R's currency and 1 percent of one’s annual income. Which of the following represents the simplified formula for computing the income tax, in Country R’s currency, for a person in that country whose annual income is “I”? A) 50 + I/200 B) 50 + 3I/100 C) 50 + I/40 D) 100 + I/50 E) 100 + 3I/100 正解是C 又臭又長的題目....我其實看不大懂第一句話... 而且average of 100 units 怎麼算出來...囧 感恩~ -- 一輩子一場夢..... -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.47.38.85 ※ 編輯: giyoshi 來自: 114.47.38.85 (09/14 16:15)
