題目
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 $100.What is the total amount the salesman was paid last week?

(1) The total amount the salesman as paid last week is equal to 10 percent of the amount of these sales last week
(2)The salesman's slaes last week total $5000

答案 D
想請問大家我列式解答A的部分對不對
設上禮拜amount of sales = x
300+(x-1000)*5%=(x-1000)*10%
所以可以解出上禮拜的amount of sales
這樣對嗎
謝謝大家了^^

我也是算這樣
不過......題目中的是100吧
