Doctors and Nurses

How many nurses does it take to support one doctor? A project-based activity asks learners to analyze state data to answer this question. Classes create polynomial functions from the data of doctors and nurses over a seven-year period. They then combine the models to create a rational function and provide a summary of their results in a technical memo.
