Based on the limited information provided, I'm estimating Marla's hourly rate to be $50. This is a very rough estimate, as it's difficult to determine a precise rate without knowing her specific skills, experience, and qualifications. However, considering her role as a small business owner, I've based my estimate on national averages for retail management and entrepreneurship. According to the Bureau of Labor Statistics, the median hourly wage for retail managers in the United States is around $15. However, this does not take into account the specific demands of the beauty industry or Marla's level of experience. Without more information, it's challenging to provide a more accurate estimate.
