Okay, let’s tackle this. So Fred has been working at Cincinnati Sub-Zero for over 50 years, which is a long time. Typically, product development managers with his level of experience in industries like manufacturing or consumer goods can charge around $50–$100 per hour. However, considering his tenure and the fact that he's still working, I'll estimate a lower rate, around $75 per hour. This is also influenced by the fact that he's not in a high-demand field like tech, but rather a more traditional industry like appliances.
