题目

1. Each week a salesperson receives a commission that is equal to 12 percent of the first $500 of sales plus 20 percent of additional sales. If the salesperson received a commission of $380 last week, what was the total amount of the sales that the salesperson made last week?

A. $1,600

B. $1,660

C. $1,860

D. $2,000

E. $2,100

答案：E

解析：$500*12%=$60; $380-$60=$320; $320/0.2=$1600; $1600+$500=$2100

2. 已知x ≠ 0，

Quantity A: x^2

Quantity B: x(x+5)

A. Quantity A is greater.

B. Quantity B is greater.

C. The two quantities are equal

D. The relationship cannot be determined from the information given.

答案：D

解析：如果x > 0, 则B > A; 如果x < 0, 则B < A，由于x值无法确定，因此两者大小无从比较，所以选D。

3. If x< y, which of the following must be true?

A. 2x< y

B. 2x> y

C. x2< y2

D. 2x-y< y

E. 2x-y< 2xy

答案：D

解析：D项不等式变化可得2x<2y，也就是条件的x

4. The table shows the frequency distribution of the random variable X. What is the median of the distribution of the Value X?

A. 1.0

B. 1.8

C. 2.0

D. 2.5

E. 3.0

答案：3

解析：题干问X这组数据的中位数。根据右侧的频率可知，总共出现了73个数字，所以中位数应该是第37个数字，所以中位数是3。

5. According to a tax rate formula for a certain year, the amount of tax owed by an individual whose annual income was between $31,850 and $77,100 was equal to a base tax of $4,386 plus 24 percent of the annual income that exceeded $31,850.According to this formula, what was the amount of tax owed by an individual whose annual income that year was $42,000?

答案：6822

解析：题干问，某一年个人收入在$31,850到$77,100之间的税收计算方式为$4,386加上超出$31,850部分的24%。问收入为$42,000的个人这一年需缴纳多少税?

所以我们可以得到所缴税的计算方式=4386+24%*(42000-31850)=6822.
