So today we're going to talk about macroeconomics...
“Supply and demand is the fundamental model of a market economy. It determines the equilibrium price and quantity.”
When supply shifts rightward while demand remains constant...

WORKED EXAMPLE
See how Learnex synthesizes a dense equilibrium slide into a scripted, narrated video explainer with animated highlights.
Consumer surplus represents the difference between the total amount that consumers are willing and able to pay for a good or service and the total amount that they actually do pay (the market price). Graphically, it is the triangular area beneath the demand curve and above the equilibrium price line.
