Worker productivity at a healthcare clinic is not measured by the number of patients handled but by the number of billable hours. The number of billable hours varies between a physician and a physician assistant.  A physician's time is billed to the clinic at a rate of 250 per hour whereas physician assistants' time is billed at a rate of 125 per hour.  On average each physician generates 25 billable hours per 40-hour workweek with 15 hours spent on administrative and supervisory responsibilities. What is the total salary both earn?
