Okay, let’s tackle this. So Dorothea has a certification as a Certified Public Accountant, which is a standard professional designation. However, the rate I'm estimating is on the lower side due to her location in the Greater Chicago Area, which may have a lower cost of living compared to other major cities. According to the Bureau of Labor Statistics, accountants in the Chicago-Naperville-Elgin, IL-IN-WI Metropolitan Division typically earn median salaries around $60,000. Considering her certification and experience, I'd estimate her hourly rate to be around $75, which is slightly above the median salary, but still on the lower end of the scale.
