When the price is $2, the quantity demanded is 10. When the price rises to $8, the quantity demanded falls to 2.
When the price is $2, the quantity demanded is 10. When the price rises to $8, the quantity demanded falls to 2. What is the value of the elasticity of demand? Is it elastic or inelastic?
Solutions
Expert Solution
* Elasticity is defined as the response of a good for a change in price. If the elasticity value is greater than 1 (absolute term) then it is called as elastic and if it is less than 1 (absolute term) then it is called as inelastic.
* So, it is calculated as percentage in Quantity demanded to percentage change in price.
Ed = ((Q2-Q1)/Q1)/ ((P2-P1)/P1) = ((2-10)/10)/((8-2)/2) = -80%/300% = -0.27
* As the value of the elasticity is less than 1 in terms of absolute value the elasticity of demand is said to be inelastic.
