Before being simplified, the instructions for 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 ? 答案是50 + I/40 我完全不知道怎麼算因為我連英文都翻譯不出來...請大家幫幫忙,謝謝
大致翻译：简化以前，R国的税收 = 一个平均数（ the average of 100 units of country R's currency and 1 percent of one's annual income) 加上 2 percent of one's annual income. 最后问你下列哪个是简化后的公式？ （这题比较搞的是：提到"100 units of units" 和最后表达要用"in country R's currency"。其实都是废话，根本不用关它）
