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

Just another thought:

Good tricky question.Important thing to realize is that the package cannot be less than 2 pounds as then for a cost of $38 there would be more than one package.

Since there is only a single package whose cost is $38 hence the package must be over 2 pounds.

In this case only the second equation i.e. 6 + 2(y) = 38 is applicable

where Y is the weight of the package and Y>2 , now we can easily get the weight of the package.
