The price elasticity of demand for laptops is -1.34.
What is the price elasticity?
Price elasticity of demand measures the how quantity demanded changes when there is a change in the price of the good.
Price elasticity of demand = midpoint change in quantity demanded / midpoint change in price
Midpoint change in quantity demanded = change in quantity demanded / average of both demands
- change in quantity demanded = 363,000 - 470,000 = -107,000
- average of both demands = (363,000 + 470,000) / 2 = 416500
- Midpoint change in quantity demanded = (107,000 / 416500) = -0.26
Midpoint change in price = change in price / average of both price
- change in price = 2550 - 2100 = 450
- average of both prices = (2550 + 2100) / 2 = 2325
Midpoint change in price = 450 / 2325 = 0.19
Price elasticity of demand = 0.26 / 0.19 = -1.34
Here is the complete question:
Suppose that during the past year, the price of a laptop computer rose from $2,100 to $2,550. During the same time period, consumer sales decreased from 470,000 to 363,000 laptops. Calculate the price elasticity of demand.
