- 1
What is price elasticity of demand?
Model answer
Price elasticity of demand measures how much the quantity demanded of a product changes in response to a change in its price.
- 2
State the formula for price elasticity of demand.
Model answer
Price elasticity of demand = percentage change in quantity demanded ÷ percentage change in price.
- 3
Why is price elasticity of demand normally a negative figure?
Model answer
Price and quantity demanded move in opposite directions, so one of the two percentage changes is negative and the result of dividing them is negative.
- 4
What value of price elasticity separates elastic from inelastic demand?
Model answer
A value of 1, ignoring the sign; above 1 demand is price elastic and below 1 it is price inelastic.
- 5
A business raises its price by 10% and quantity demanded falls by 4%. Calculate the price elasticity of demand.
Model answer
Price elasticity of demand is −0.4, because −4 divided by 10 is −0.4, so demand is price inelastic.
- 6
A business cuts its price from £20 to £18 and weekly sales rise from 4,000 to 5,000 units. Calculate the price elasticity of demand.
Model answer
Price elasticity of demand is −2.5, because quantity rose by 25% while price fell by 10%, and 25 divided by −10 is −2.5.
