Okay, let’s tackle this. So Patti has 48 years of experience, which is extremely long. Typically, professionals with this much experience can command very high rates. However, Patti's skills and experience seem to be more general, not specialized. She has a background in nursing, but that's not directly related to her current role. She's also worked in various fields like contract negotiation, purchasing, and management. These skills are valuable, but not as rare as those required for high-paying tech or finance roles. Considering her experience, I'd estimate her rate to be on the lower side of the scale. Maybe around $75 per hour, considering she's not in a high-demand field and her experience is more general. Some professionals with similar experience might charge $100-$200 per hour, but Patti's skills and background don't quite justify that level.
