Price elasticity of demand = % change in Qty demanded / % change in price
X = 12% / -4% = -3 - Answers If the price decrease by 4%. As a result, the quantity demanded
increases by 12%. The price elasticity of demand is
If demand for a good is inelastic (the price elasticity of demand is less than 1), an increase in
price increases total revenue. - Answers What is the relationship between elasticity and revenue?
Equal to 1 - Answers At a 7% reduction in the price of a product has zero effect on the dollar
amount of consumer expenditure on the product. The price elasticity of demand is:
buyer responsiveness to price changes. - Answers What does the price elasticity of demand
coefficient measure
An elastic demand or elastic supply is one in which the elasticity is greater than one, indicating a
high responsiveness to changes in price. An inelastic demand or inelastic supply is one in which
elasticity is less than one, indicating low responsiveness to price changes. - Answers What is
the characteristic of the demand for a commodity that is elastic or inelastic or unit elastic?
- Answers What is unit elastic? When the price of a good goes up and demand is unit elastic,
what would happen to the total revenue?
