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.

答案是D，我觉得是C啊。。。。

指尖墨痕

题意：工资=固定工资300+5%(x-1000)
其中x就是total sale,题目要求销售人员的工资，解出x以后就可以代入了
1)300+5%(x-1000)=0.1*x
一元一次方程，可以求出x
2）直接将x=5000代入
所以选d哦：）
