Hello I am a Grade 12 student and need some help with demand and supply scenarios. It asks the effect a personal vehicle; road and parking tax would have on the demand/supply for gasoline. Does this mean how a personal vehicle AND parking tax would effect it, or just simply having a personal vehicle and being charged parking tax?

Also, how would a wheat tax effect the supply and demand graph for wheat and then if a floor price were introduced? Thank you to anyone who can help me with this.
