New Time Videos (NTV) is a new online video rental service. In the field, it is trying to compete by offering its customers access to all of the major new video releases in one business day. That is, if you order a video from NTV, you can expect it in one business day from the time when you placed the order. When you are done with the video, you simply drop it in the prepaid mailing envelope and return it. All videos arrive in a sorting facility located in the Midwest where envelopes with the videos are opened, checked (right video with the right sleeve, no scratches, no cracks, no dirt on the videos), and made ready to be sent out again. As the manager of this facility, your goal is to turn the returned videos around in 6 hours (a shift is 8 hours long). You have the following information:

Inventory of the video 450,000 per shift
Throughput 345,000 per shift
