l. Elasticity and Taxation: Consider the following market demand curve for cigarettes: Qd = 75-.5P. When the market price is $10, market demand is 70 units. 1When price rises to $12, the market demand curve alls to 69 units. a. Calculate the price elasticity of demand as the price rises 'om $10 to $12. Explain & interpret in words. b. Ifthe government creates a per-unit tax of $2 per pack of cigarettes, effectively causing this price increase, how much revenue will the government raise? c. Explain why the government would use a per-unit tax on cigarettes instead of other possible interventions to correct the market failure associated with the negative externalities of smoking. (1.
