Within a group of 200 faculty members who have been at a well-known university for less than 15 years (i.e., since before the salary curve levels off) the equation relating salary (in thousands of dollars) to years of service is 5 0.9X 1 15. For 100 administrative staff at the same university, the equation is 5 1.5X 1 10. Assuming that all differences are significant, interpret these equations. How many years must pass before an administrator and a faculty member earn roughly the same salary?
