A certain company charges $6 per package to ship packages weighing less than 2 pounds each.For a package weighing 2 pounds or more, the company charges an initial fee of $6 plus $2 per pound.If the company charged $38 to ship a certain package, which of the following was the weight of the package, in pounds?

(A) 16

(B) 17

(C) 19

(D) 20

(E) 22

答案是A ,不过我自信满满的算出来等于18，最后一看，根本没有这个选项。。。这种题，不是应该说 6美金包括2pounds的重量+多出的重量*2吗？如果根据答案推倒，那就之前的6美金是个什么？。。。。不明白，求助~~谢谢！

the company charges an initial fee of $6 plus $2 per pound的意思是说所有的重量X 2+6
