If scientists discover that steamed milk, which is used to make lattés, prevents heart attacks, what would happen to the equilibrium price and quantity of lattes? a. Both the equilibrium price and quantity would increase.
b. Both the equilibrium price and quantity would decrease.
c. The equilibrium price would increase, and the equilibrium quantity would decrease.
d. The equilibrium price would decrease, and the equilibrium quantity would increase.

a. Both the equilibrium price and quantity would increase.

Explanation:

The point on a demand-supply graph where the demand curve and the supply curve intersects is known as the point of equilibrium.

If scientists discover that steamed milk, which is used to make lattés, prevents heart attacks, what would happen to the equilibrium price and quantity of lattés is that, both the equilibrium price and quantity would increase.

This simply means that, whatever makes the factors of production such as, land, labor, entrepreneurship, capital, or efficiency to either go up or down would certainly result in fluctuations in the economy of a particular country.

Aggregate supply (AS) refers to the total quantity of output (goods and services) that firms are willing to produce and sell at a given price in an economy at a particular period of time.

Aggregate demand (AD) can be defined as the total quantity of output (final goods and services) that is demanded by consumers at all possible price levels in an economy at a particular time.

On a standard Aggregate demand (AD)-Aggregate supply (AS) curve, the y axis denotes the Price (P) of goods and services while the x axis typically denotes the Output (Q) of final goods and services.

In the short-run, a rightward shift in the aggregate supply (AS) curve causes output to increase and result in a price fall (lower price) while a rightward shift in the aggregate demand (AD) curve also cause output to increase and rise in prices.

The short-run nominal fluctuations basically cause a change in the level of production. In the short-run, as a result of a shift in the aggregate supply; an increase in money consequently to result in increase the level of production (output).

Hence, more goods are produced as a result of the increased output (supply) and more goods would be purchased as a result of their lower prices.
