Suppose that a 20% increase in the price of gasoline causes a 5% decrease in the consumption of gasoline and a 30% drop in the sales of SUVs. What can you say about elasticities?
Answer
the elasticity of demand =%change in quantity /%change in price
=-5/20
=-0.25
=0.25 (absolute value)
the elasticity of demand for gasoline is 0.25 and it is inelastic as the elasticity is below 1.
=======
cross-price elasticity=%change in quantity of a good /%change in the price of the good
=-30/20
=-1.5
The cross-price elasticity is negative so Gasoline and SUVs are complements

8. Refer to the "In the News" below: In the News: SUV Sales Drop with Gasoline Price Rise Analysts say that with the increase in gasoline prices comes a drop in SUV sales and trade-in values at dealerships. The U.S. Department of Energy said that during the past week, U.S. gasoline prices topped $3 a gallon—the highest level since October 2008. .. According to Alec Gutierrez, lead analyst for vehicle evaluation at Kelley Blue Book, SUV sales have decreased about...
QUESTION 4 Suppose a 10% decrease in the price of pianos causes a 40% increase in piano sales. The elasticity of demand for pianos is
The demand for gasoline is inelastic, a 5 percent increase in the price of gasoline will: O decrease the quantity of gasoline demanded by more than 5 percent. O increase the quantity of gasoline demanded by less than 5 percent O increase the quantity of gasoline demanded by more than 5 percent. O decrease the quantity of gasoline demanded by less than 5 percent.
