A secretary must be trained for 5 days before becoming eligible for assignment to clients. Each new secre- tary is trained by a qualified secretary. There are 65 working days in each quarter, and at the beginning of the spring season there are 120 qualified secretaries on the payroll. The secretaries (both new and qualified ones) earn a salary of $800 a month. During each quarter, the company loses 15% of its personnel (including secretaries trained in the previous quarter).
