Control Flow And Queue's

A queue just preserves the order in which items arrived into it. This helps model real world problems around waiting in your turn or in line.

Directions: Write a ruby script to do the following with a queue.

Scenario: you have a store and you're writing a script to help calculate a quick receipt. The one problem is that every 3rd and 5th item a customer buys is on sale. Every 3rd item is 10% off and every 5th item is 20% off, but also, an item that is both a 3rd and 5th item is 30% off.
