Okay, let’s tackle this. So Mary Ann has a very long tenure as a librarian, which is impressive. However, her salary range is not explicitly mentioned. According to the Bureau of Labor Statistics, librarians in the New York-Newark-Jersey City, NY-NJ-PA metropolitan area have a median annual salary of around $60,000. Considering her extensive experience, I would estimate her hourly rate to be lower than the median. A more suitable estimate would be around $75 per hour, considering her skills in Microsoft Office and public speaking, which are valuable assets in the industry.
