Answer:
a)The equilibrium price of gasoline was probably below the price ceiling.
Step-by-step explanation:
Price ceilings take place when the government imposes a maximum selling price for a good. While price floors take place when government imposes a minimum selling price for a good. In order for any of them to be able to cause any type of effect, or even be noticed, they must actually influence the sales price. E.g. the price ceiling must be lower than the market price of gasoline. Imagine the market price of gasoline is $4 per gallon and a price ceiling of $10 per gallon is imposed. It would actually have no effect at all. In this same situation, if hte government instead established a price floor of $2 per gallon, it would also make no effect at all since the market price was already higher.
