Economic systems—like market, command, and mixed—play a big role in what people buy and how much it costs.

1. Market Economy:

   • In a market economy, what people buy is based on supply and demand. For example, if a brand-new smartphone comes out and everyone wants it, the price might go up fast because so many people are trying to buy it.

2. Command Economy:

   • In a command economy, the government makes all the choices. For instance, if a government sets the price of bread lower than what stores would normally charge, there could be not enough bread for everyone, which limits what people can buy.

3. Mixed Economy:

   • This type combines both market and command systems. Take healthcare as an example; the government sets some prices, but private companies also offer services, giving people different choices.

Basically, how an economic system is set up affects what people can purchase and how much they have to pay for it!
