Wrong! - A tax credit given to buyers of electric vehicles raises the amount buyers are willing to pay sellers, so it increases demand. Does the price received by sellers change? The price paid by buyers includes the tax credit. Does the price paid by buyers rise or fall?
Well Done! - A tax credit has the opposite outcome of a tax. A tax credit given to buyers of electric vehicles raises the amount buyers are willing to pay sellers, so it increases demand. An increase in demand raises the price received by sellers but by less than the amount of the tax credit. The price paid by buyers falls to equal the price received by sellers minus the tax credit.
