问题如下图：
选项：
A. 
B. 
C. 
老师，请问这个题为什么不选B？代入公式时，加和-DX，前面有个负号，level项自带负号，又是减少，所以level项目前面符号为负，同理曲度项前面为正，所以最后加和为负选B

NO.PZ201701230200000307 老师，请问什么情况下需要考虑权重啊，计算价格变化的那个公式是考虑了权重后的加权平均数，为什么这道题不用加权呢？ 谢谢老师啦！
NO.PZ201701230200000307 题干中表格level数值为负的，是one viation increase的数据；而算出来的结果为正的0.0389，所以应该是相反 变成crease？谢谢老师。
