题目如下: Before being simplified, the instructions for computing income tax were to add 2 percent of one's annual income to the average (arithmetic mean) of 100 units of the country's currency and 1 percent of one's annual income. Which of the following represents the simplified formula for computing the income tax for a person whose annual income is I ? 答案是50+I/40 我算的是100+3I/100 求指点~~~ |
