You've produced an entertaining and educational newsletter on Linkedln for the last year. Each edition earns more engagement and subscribers than the last. While being mindful of your limited budget, what is the most strategic way of repurposing this newsletter for a wider audience? Develop an audio adaptation reading through each edition. Develop a weekly discussion in Discord for each edition. Develop a video adaptation visualizing each edition. Dodcast with a new episode for each edition.

Suppose a firm had a production function with linear isoquants, implying that its two inputs were perfect substitutes for each other. What would determine the firm's expansion path in this case? For the opposite case of a perfect complements production function, what would the firm's expansion path be?
