3. One football season Domino’s Pizza, a corporate sponsor of the Washington Redskins (a football team), offered to reduce the price of its $8 medium-size pizza by $1 for every touchdown scored by the Redskins during the previous week. Until that year, the Redskins weren’t scoring many touchdowns. Much to the surprise of Domino’s, in one week in 1999, the Redskins scored 1 touchdown. (Maybe they like pizza.) Domino’s pizzas were selling for $7 a pie! The quantity of pizzas demanded soared the following week from 50 pies an hour to 60 pies an hour. What was price elasticity of demand for Domino’s pizza?
4. When tolls on the Dulles Airport Greenway were reduced from $2.00 to $0.75, traffic increased from 12,000 to 34,000 trips a day. Assuming all changes in quantity were due to the change in price, what is the price elasticity of demand for the Dulles Airport Greenway?
5. Determine the price elasticity of demand if, in response to an increase in price of 20%, quantity demanded decreases by 25%.
6. When the price of ketchup falls by 17%, the demand for hot dogs rises by 4%b. Income rises from $75,000 to $90,000; demand increases (at a constant price) from 50 to 55..
A. Calculate the cross-price elasticity of demand.
B. Are the goods complements or substitutes: .
C. In the original scenario, what would have to happen to the demand for hot dogs for us to conclude that hot dogs and ketchup are substitutes?
1. The demand for hot dogs would have to decline.
2. The demand for hot dogs would have to remain unchanged.
3. The demand for hot dogs would have to rise.
7. Calculate the income elasticities of demand for the following:
A. Income rises by 5%; demand increases by 5%.
