The price of cigars is $10, with a quantity demanded of 1,000 per day. If the price increases to $12, the quantity demanded declines to 800 per day. What is the absolute value of elasticity of demand?

PED = - 1

Explanation:

The PED or price elasticity of demand measures the sensitivity of quantity demanded to changes in price level. It is calculated by taking the percentage change in quantity demanded, which results from a change in price level, and dividing it by the percentage change in price level.

PED = percentage change in Quantity demanded / Percentage change in price

PED = [(800 - 1000) / 1000]  /  [(12 - 10) / 10]

PED = - 1
