Mason runs a lemonade stand. What happens to the demand for his lemonade when he increases the price?

• It increases

• It decreases

• It stays the same

• It becomes unlimited

Benjamin runs a lemonade stand and sets the price of lemonade above the equilibrium price. What will likely happen?

• The price will increase further

• Sellers will lower the price to sell extra inventory

• Consumers will rush to buy more

• The product will become more popular

Answer explanation

When a product is priced above equilibrium, demand decreases while supply increases, leading to excess inventory. To sell this inventory, sellers will lower the price, making this the most likely outcome.

Samuel is selling lemonade at a price below the market equilibrium. What will likely happen?

• There will be a shortage

• The price will drop further

• Sellers will produce more than needed

• There will be a surplus

Answer explanation

When a product is priced below equilibrium, demand exceeds supply, leading to a shortage. Sellers cannot meet the demand, which may drive prices up until equilibrium is reached.

When a shortage of bicycles happens in the city, what is the natural market response?

• Price increases to reduce demand and encourage more supply

• Price decreases to increase supply

• Price stays the same until the government intervenes

When a shortage occurs, prices naturally increase. This rise in price helps to reduce demand and incentivizes suppliers to produce more, ultimately balancing the market.
