Answer:
D) The price of gasoline will increase.
Step-by-step explanation:
Since the quantity demanded of gasoline increases during the summer and holidays, the equilibrium price will rise. This simply follows the law of supply and demand.
Another factor that could determine how much the price of gasoline will increase, is whether or not the supply of gasoline also increases during summer and the holidays. If the supply of gasoline increases, then the increase in the equilibrium will be lower than if the supply of gasoline remains unchanged.
