b. Studies indicate that the price elasticity of demand for cigarettes is about -0.2. If a pack of cigarettes currently costs $4, and the government wants to reduce smoking by 25 percent, by how much should it increase the price?

Suppose that the price elasticity of demand for a packet of cigar is -0.85 and the price elasticity of supply is 1.5 at market equilibrium. As a result of an increase on sales tax, the new equilibrium price rises by 15%. (a) What is the percentage change in quantity demanded of cigar? Show your calculation.

When the price of A increase by 30%, the consumption of the good decreased by 10%, what is the price elastic of demand? Will the total revenue of selling the good increase or decrease when the price of good A increase? When the price of A increase by 10%, the consumption of the good B increases by 20%, what is the cross-price elasticity of demand of B with the change of price of A?

If the price of product X increases from $10 to $12, the quantity demanded for gasoline (X) will fall from 100 to 82 and the quantity demanded for product Y also falls from 90 to 63 but the quantity demanded product Z will increase from 50 to 76. a.What is the price elasticity of demand for X?b.What is cross-price elasticity of demand for Ywith respect to price X? What are X and Y?c.What is cross-price elasticity of demand for Zwith respect to price X? What are X and Z?

When the price of a good is lowered from £350 to £200 the quantity demanded increasesfrom 600 to 750 units. Calculate elasticity of demand.

the % change in price of spaghetti between prices of $18 and $20 is 10.53. the elasticity of demand between the prices of $18 and $20 is -1.69. So, what is the % change in the quantity of spaghetti when the price changes from $18 to $20?
