Question

Tim has 39 pairs of headphones and 13 music players. Tim wants to sell all of the headphones and music players in identical packages.

Answer 1

Then Tim would put three headphones with one music player in each package.

Explanation:

So, you'd have to divide 39 (pairs of headphones) by 13 (music players) to get three. That means that for every music player sold, he could give three headphones with it.
