Why do prices change when sellers want to make more money?

Prices change when sellers want to make more money because they’re trying to balance what people are willing to pay and how much they want to earn.

Imagine you have a lemonade stand. On a hot day, lots of kids come by thirsty and are happy to pay $2 for a glass of lemonade. But if it’s a cool day, fewer kids stop by, and you might only be able to sell each glass for $1.

Now suppose you want to make more money. You could raise the price, like going from $1 to $2, so that when people still buy your lemonade, you earn more per glass. But if you raise it too much, some kids might think it’s too expensive and decide not to buy anymore.

This is just like how sellers in real life work: they look at how many people want their product and adjust the price to make sure they can sell enough while earning more money. It's all about finding the right price that works for both the seller and the buyer, kind of like a fun game of “how much do you want to pay?”
