What's even more interesting, I gave GPT-4 a follow-up instruction: > Please provide a single mathematical equation that could be used to solve this problem. And it gave me the following answer: > Sure, let's represent the required inventory as I, the desired annual revenue as R, the markup factor as M, and the inventory turnover as T. We can create a single equation to solve this problem: > I = (R / M) / T > In this problem, R = $3,000,000, M = 4, and T = 1.5. Plugging these values into the equation will give you the required inventory (I). To me that a language model can do this is simply mind-blowing.
