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
請問根據黃色部分
條件1的列式到底是300+5%(x-1000)=0.1*x還是 300+5%(x-1000)=0.1*(x-1000)  呢?
因題目有說超過1000才有分紅可拿呀 所以應該是要乘上(x-1000)吧?

是300+5%(x-1000)=0.1*x

的确是超过1000才有分红，但是条件一里说的是这个salesman得到的总报酬刚好等于总销售收入的百分之十，所以是0.1X,  
他们只是数字上刚好相等，并没有联系。所以你不用纠结是不是超过1000才有分红拿。
