Let x = the weight of the package (in pounds)
So, the shipping cost = $6 + 2x

We're told the shipping cost is $38.
So, we can write: 6 + 2x = 38
Subtract 6 from both sides: 2x = 32
Solve: x = 32/2 = 16

Answer: A

Hi All,

We're told that a certain company charges $6 per package to ship packages weighing less than 2 pounds each. However, for a package weighing 2 pounds or more, the company charges an initial fee of $6 plus $2 per pound. We're told that a certain package cost $38 to ship. We're asked for the weight, in pounds, of that package. This question can be solved by TESTing THE ANSWERS.

Let's TEST Answer B: 17 pounds

According to the pricing 'rules' a 17 pound package would cost $6 + 17($2) = $40. This is TOO EXPENSIVE. Thus, the package must weigh LESS than 17 pounds. There's only one answer that fits...

Final Answer: A

Letting n = the weight of the package, we can create the equation:

38 = 6 + 2n

32 = 2n

16 = n
