Imagine you're the world's best pizza maker (every teenager's dream, right?). The time it takes to make a fresh pizza from scratch (let's call it our "primary product") is usually more than if you were just heating up a frozen pizza (a "manufactured product"). This difference impacts how much pizza you can supply when more people suddenly want your mouthwatering pizzas (higher demand).

Imagine a crowd of hungry teenagers coming to your pizzeria after a football match. They all want pizzas right now! If you're making fresh pizzas, it'll take some time - you have to knead the dough, add the toppings, and bake it. On the other hand, if you've pre-made frozen pizzas, you can just pop them in the oven, and voila! More pizzas in less time. So, you can respond quicker to the sudden pizza demand with your "manufactured" frozen pizzas than your "primary" fresh pizzas.
