Write the formula for the
Formula for price elasticity of demand.
Explanation of Solution
Price-elasticity of demand is the responsiveness of the quantity demanded to the change in price. The formula for price elasticity of demand is percentage changes in quantity demanded divided by percentage changes in price. It can be symbolically expressed as follows:
The price elasticity of demand is measured by using the slope of the demand curve. Because, the slope states that how much the quantity changes according to the change in price.
Concept Introduction:

- (Other Elasticity Measures) Complete each of the following sentences: a. The income elasticity of demand measures, for a given price, the __________ in quantity demanded divided by the __________ income from which it resulted. b. If a decrease in the price of one good causes a decrease in demand for another good, the two goods are __________. c. If the value of the cross-price elasticity of demand between two goods is approximately zero, they are considered __________.arrow_forwardUsing the following equation for the demand for a good or service, calculate the price elasticity of demand (using the point form), cross-price elasticity with good x and income elasticity. Q=82P+0.10I+Px Q is quantity demanded, P is the product price. P1 is the price of a related good, and I is income. Assume that P= $10, I = 100, and Px = 20.arrow_forwardThe equation for a demand curve is P=483Q. What is the elasticity in moving from quantity of 5 to a quantity of 6?arrow_forward
- Suppose a movie theater raises the price of popcorn 10 percent, but customers do not buy any less popcorn. What does this tell you about the price elasticity of demand? What will happen to total revenue as a result of the price increase?arrow_forwardThe quantity supplied of a good rises from 120 to 140 as price rises from 4 to 5.50. What is the price elasticity of supply of the good?arrow_forwardWhat does a price elasticity of demand of 0.39 mean?arrow_forward
- As the price of good X rises from 10 to 12, the quantity demanded of good Y rises from 100 units to 114 units. Are X and Y substitutes or complements? What is the cross elasticity of demand?arrow_forwardThe quantity demanded of good X rises from 130 to 145units as income rises from 2,000 to 2,500 a month. What is the income elasticity of demand for good X?arrow_forwardIsabella always spends $50 on red roses each month and simply adjusts the quantity she purchases as the price changes. What can you say about Isabella's elasticity of demand for roses?arrow_forward
