Final answer:
The formula for elasticity of demand is the percentage change in quantity demanded divided by the percentage change in price. In this case, the elasticity of demand is approximately -0.53.
Step-by-step explanation:
The formula for elasticity of demand is the percentage change in quantity demanded divided by the percentage change in price.
In this case, the percentage change in price is 15% and the percentage change in quantity demanded is -8%. To calculate the elasticity of demand, we divide -8% by 15%. This gives us an elasticity of demand of approximately -0.53.
