Okay, let’s calculate this. So Betty Lewis is a certified public accountant with a strong background in financial management and analysis. Her certification from a reputable issuer adds credibility. Location is St Louis, Missouri, which is the 2nd largest city in the US. According to the Bureau of Labor Statistics, the average hourly rate for accountants in the US is around $40. However, this can vary depending on experience, industry, and location. For a certified public accountant in a mid-sized city like St Louis, I would estimate a rate around $75 per hour, which is slightly higher than the national average. This is because certified public accountants with strong credentials and experience can command higher rates.
