Answer:
Price Ceiling regulations prohibit the price of a good or service from being higher than a set price known as the Price Ceiling.
Price Floor regulations prohibit the price of a good or service from being lower than a set price known as the Price floor.
When either Price Ceiling or Floor is said to be nonbinding, it means that it does not affect the market/ equilibrium price of the good or service.
Binding Ceilings or Floors affect the market/ equilibrium price.
Due to new regulations, fast-food restaurants that would like to pay better wages in order to hire more workers are prohibited from doing so. BINDING PRICE CEILING.
The Fast-food restaurants cannot pay above a certain amount which makes this a Price Ceiling. It is binding because the Market wants to pay higher wages to hire more people but cannot therefore the price ceiling is having an effect on the equilibrium price.
The government prohibits fast-food restaurants from selling hamburgers for more that $5 each. BINDING PRICE CEILING.
Fast-food restaurants are not allowed to sell above the set price of $5 which makes this a price ceiling. It is Binding because the equilibrium price is $7 which means that fast-food restaurants are forced to sell below the equilibrium price therefore this Price ceiling affects the equilibrium price.
