Okay, let’s tackle this. So Karen Huston has been running her own business for over 48 years, which is a significant amount of experience. Her skills in graphic arts, photography, and advertising are in demand. However, her role as an entrepreneur means she's likely self-employed or has a unique business structure. According to the Bureau of Labor Statistics, experienced graphic designers can earn around $50-$75 per hour. Considering Karen's extensive experience and diverse skill set, I'd estimate her hourly rate to be around $125. This is slightly below the average rate for experienced graphic designers, but taking into account her entrepreneurial background and the fact that she's been in business for so long, it's a reasonable estimate.
