    Linear Programming (LP) Problem. Assuming these numbers to be representative, and that transfers /re-enrollment occur twice yearly, what will be the market share distribution at the end of the next cycle? What will be the market distribution at the end of the next year? What will be the market distribution at the end of the 5-year planning period of interest to the Dean? If changes are not made that effect a change in the enrollment rate, the assumptions for a steady state population (exits=entrants) hold true, and there are no other significant schools entering the competition that changes the numbers for "other" category, what will be the distribution when the competition for students "steady out" (reaches steady state)?
