A DVD rental company has three locations, which we designate as P, Q, and R. When a DVD is rented at one of the locations, it may be retuned to any of the three locations. Suppose that the company starts with 100 DVD's at each location and that the weekly distribution of DVD's for each location can be summarized as follows: Weekly Distribution Location P: 82% stay at P, 8% go to Q, 10% go to R. Location Q: 3% go to P, 94% go to Q, 3% go to R. Location R: 7% go to P. 6% go to Q. 87% go to R.

Using linear algebra principles for markov chain, how would I determine the equilibrium state of the the system to figure out how many DVDs would be at location P, Q, and R?

A DVD rental company has three locations, which we designate as P, Q, and R. When a DVD is rented at one of
the locations, it may be retuned to any of the three locations. Suppose that the company starts with 100 DVD's
at each location and that the weekly distribution of DVD's for each location can be summarized as follows:
Weekly Distribution
Location P: 82% stay at P, 8 % go to Q, 10% go to R.
Location Q: 3% go to P, 94% go to Q, 3% go to R.
Location R: 7% go to P, 6% go to Q, 87% go to R.

Follow-up Question

Why is the equilibrium state for location R 97 instead of 100?  I thought it would be 10+3+87=100?  Where is 97 coming from for R?
