紧急求助tt gwd 3-29、36

Q29:

Each week a certain salesman is made a fixed amount equal to $300 plus a commission equal to 5 percent of the amount of these sales that week over $1,000.  What is the total amount the salesman was paid last week?

(1)   The total amount the salesman was paid last week is equal to 10 percent of the amount of these sales last week.

(2)     The salesman’s sales last week total $5,000.

                  

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.

答案是d,我选a,理由是设salary为y,slaes为x,建立函数关系有y=300+0.05(x-1000),那么a选项可以表达为,y/x=(300+0.05(x-1000))/x=0.1, 即可求出x

Q36:

If M is the least common multiple of 90, 196, and 300, which of the following is NOT a factor of M?

 

A.     600

B.     700

C.     900

D.     2,100

E.      4,900

我怎么觉得这四个选项全是m的因子啊?

Q29 (2)5000=300+(X-1000)0.05  so (2) is also OK. the anwer should be D.

Q36 A is the answer because M=2x2x3x3x5x5x7x7=100x3x3x7x7 while 600=100x2x3

告诉你销售额算收入  没看清楚题目吧

300+(5000-1000)*0。05就行了

90196和7有什么关系 抄错题目了吧?
