1. A salesperson received a 6-percent commission on the amount of total sales up to and including $10,000, and an r-percent commission on the amount of total sales over $10,000.If the salesperson received a total commission of $920 on total sales of $14,000, what was the value of r?
1。营业员的消售额在10,000之内包括10,000.提成是6%.当消售额超过10,000提成是R%.现在他的总收入是920元,总消售额是14,000问你R是多少? 10000*6%+(14000-10000)*r%=920 这个式子会解吧.如果这个式子再不会,我也没有办法了. 结果R=8% |
