Suppose the price of widgets rises from $5 to $7 and consumption of widgets falls from 25 widgets a month to 15 widgets. Calculate your price elasticity of demand of widgets. What can you say about your price elasticity of demand of widgets? Is it Elastic, Inelastic, or Unitary Elastic? Why? Please show your work.

Unitary elastic

Elasticity of demand is unitary elastic because the absolute value of elasticity is equal to 1.

Explanation:

Elasticity of demand measures the responsiveness of quantity demanded to changes in price.

Elasticity of demand = percentage change in quantity demanded / percentage change in price

Percentage change in quantity demanded = (25 - 15) / 25 = 0.4 × 100 = 40%

Percentage change in price = ($5 - $7) / $5 = 0.4 × 100 = 40%

Elasticity of demand = 40% / 40% = 1

If coefficient of elasticity is equal to 1, demand is unit elastic. It means that a change in price has an equal efect on the quantity demanded. Quantity demanded has an equal and proportional change to changes in price.
