Please help me with this questions:

Gas prices fluctuate often and in both directions :

• How responsive consumers will be to the price change when these fluctuations occur due to changes in supply? Why? Use the various determinants of elasticity to explain your answer.
• How does the price elasticity of demand for gasoline impact the effectiveness of taxes on gasoline aimed at correcting a negative externality?

Consider incorporating the supply-and-demand model to demonstrate the elasticity of demand for gas and to show the effects of tax on the market for gas
