Okay, let’s tackle this. So Lynn has 54 years of experience as a bookkeeper, which is extremely rare. Typically, bookkeepers with this level of experience can charge higher rates. However, considering her self-employed status and location in Missoula, Montana, I'll estimate a lower rate. According to the Bureau of Labor Statistics, bookkeepers in Montana can earn around $40,000 per year. Let’s assume Lynn charges a premium for her expertise and experience. A common rate for experienced bookkeepers is around $75 per hour. However, this is a very rough estimate and may not reflect Lynn's actual earning potential.
