Market transactions refer to the buying and selling of goods and services between buyers and sellers. These transactions can occur in various settings, such as physical stores, online platforms, or financial markets. The price of items is typically determined by supply and demand, where higher demand can lead to increased prices, while excess supply may lower them. In a market transaction, both parties usually agree on a price before the exchange takes place. This process can involve negotiation, especially in cases of real estate or art sales. Successful transactions contribute to the overall economy by facilitating trade and enabling businesses to thrive.
