Question 2.56

2.56 Inventory of Blu-Ray players

A local consumer electronics store sells exactly eight Blu-Ray players of a particular model each week. The store expects no more shipments of this particular model, and they have 96 such units in their current inventory.

  1. Give an equation for the number of Blu-Ray players of this particular model in inventory after x weeks. What is the slope of this line?
  2. Draw a graph of this line between now (Week 0) and Week 10.
  3. Would you be willing to use this line to predict the inventory after 25 weeks? Do the prediction and think about the reasonableness of the result.
