Suppose the price of gasoline decreases from $4.20 to $2.00, and in response quantity demanded increases from 10600 to 11200. Using the mid-point formula, what is the price elasticity of demand

0.079

Explanation:

Price elasticity of demand using midpoint formula can be calculated as follows

Formula

Elasticity of demand = (change in quantity/average quantity)/(change in price/average price)

Calculation

Elasticity of demand = (600/10,900)/(-2.1/3.05)

Elasticity of demand =-0.055 / -0.688

Elasticity of demand =-0.079

working

Change in price (2-4.1) = -2.1  

Average price (2+4.1)/2=3.05

Change in quantity (11,200-10600) = 600

average quantity (11,200+10,600)/2 = 10,900

The elasticity of demand is inelastic as the elasticity is below 1.
