Suppose that, in a competitive market without government regulations, the equilibrium price of milk is $2.50 per gallon, and employees at grocery stores earn $21.50 per hour. Indicate the following whether each of the statements is an example of a price ceiling or a price floor and whether it results in a shortage or a surplus or has no effect on the price and quantity that prevail in the market. a. There are many teenagers who would like to work at grocery stores, but the minimum-wage law sets the hourly wage at $25.00.
b. The government has instituted a legal minimum price of $2.30 per gallon for milk.
c. The government prohibits grocery stores from selling milk for more than $2.30 per gallon.

Explanation:

at price ceiling we have price set at a maximum level. it cannot be raised beyond this level. At binding price ceiling, price would be set to be lower than what is the equilibrium price level.  a non binding price ceiling is set to be higher than equilibrium level.

At price floor, price is set to a particular minimum level.  It cannot fall lower than this. At binding price floor, price is higher than equilibrium price' at non binding price floor, it is set to be lower than equilibrium price level.

this expalnation should help us to answer this question.

(a) Many teenagers would like to work but minimum wage is set at 25.00 we have Price floor, Binding

(b) Government instituted legal minimum price of a gallon of milk at $2.30 we have Price floor, Non-binding

(c) if the Government prohibits from selling milk for more than $2.30 per gallon then we have Price ceiling, Binding
