Imagine that a new education program was created to service inmates who do not hold a high school diploma. The inmate population is approximately 1500 on any given day, and only 10 percent are serving life sentences. The majority of inmates will be released within 3 years, and the average age of the inmate population is 19.

Since this is not a mandatory program, how should programmers determine the number of General Education Development (GED) instructors to hire?
What factors should be considered in determining the number of instructors hired to staff the education program? Should there be any restrictions in terms of inmate eligibility?
