Which of the following statements about aggregate demand and supply curves are true? Select all that apply.

Aggregate demand and supply curves help us understand how the total demand for goods and services in an economy interacts with the total supply. The aggregate demand curve shows the total amount of goods and services that consumers, businesses, and the government want to buy at different price levels. In contrast, the aggregate supply curve represents the total amount of goods and services that producers are willing to sell at various price levels. For example, if the economy is doing well, aggregate demand might increase because people have more money to spend, leading to higher prices and more production. Understanding these curves is important because they help us analyze how changes in the economy, like increased spending or changes in production costs, can affect overall economic activity.
