Okay, let’s tackle this. So Peter Ripp has 11 years of experience as a Registered Nurse. According to the Bureau of Labor Statistics, the median hourly rate for Registered Nurses in Wisconsin is around $34. However, this can vary depending on location, experience, and industry demand. Considering Peter’s experience and location in Waunakee, WI, a relatively affluent area, I would estimate his hourly rate to be on the higher side of the median. Let’s assume a 10-20% premium for his experience and location. This puts his estimated hourly rate at around $38-$45. Given the lack of specific data on nursing rates in this area, I'll take a conservative estimate of $45 per hour.
