If merchants only get a small amount from what they sell, then how do they make profit if one or more of their product isn’t sold ?

Question

Let’s take a phone merchand for example. Let’s say that he sells the phones for 500$, but his income from a phone is 50$ because they are sold 450$ from the factory. So, if just ONE phone isn’t sold, he’d lose 450$, and he’d need to sell 9 phones (450÷5) just to come back to the starting point.

This question also works for any kind of merchandizing, including food (which becomes unsellable after a few days unlike phones).

So how do they make profit of it ? I’m confused

This post is the same as a post I made 1 hour ago that corrects some words, sorry for my bad english.

Answer 1

The phones sale just gets the customer in the door, it’s the accessories they actually make money on. Things like cases, screen protectors, and all that stuff cost like a $1 to make but they get sold for $40.
