By using demand and supply diagrams, show the effect of the following events on the market for sport utility vehicles (SUVs). SUVs are a substitute for cars.

a. Government regulations, applied only to cars, require that cars weigh less. As a result, when a car and an SUV crash, the car’s occupants are more likely to be injured or killed than those in the SUV.

b. More car companies build and supply SUVs.
c. Higher gasoline prices raise the cost of driving SUVs more than the cost of driving cars because SUVs get fewer miles per gallon.
d. The government imposes a tax on suppliers for each SUV they sell.
