The reason I can tell you what opportunity cost is, is because one day when I was playing Super Mario Kart on my couch, my friend Emmet walked in, and he said, "How long have you been playing Super Mario Kart?"
Razlog zašto vam mogu reći  što je oportunitetni trošak, je zato što sam jedan dan igrao Super Mario Kart na sofi, i moj prijatelj Emmet je ušao i rekao, "Koliko dugo već igraš Super Mario Kart?"
