网考网参考答案：D
网考网解析：
alone is sufficient; we know the 8 cars over the quota will receive a total of $4,000 in extra commission (8×$500), so divide the remaining money by $250 per car to determine the quota--$3,500/$250 = 14 cars. (2) alone is sufficient; $1,750 at $250 per car means that he sold 7 cars, and if 7 is half of the quota, then the quota is 14. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
