Mathematically, this is expressed as -60%/20% = -3. The price elasticity of demand for throw pillows is 3. A price elasticity of demand of 3 indicates an elastic price elasticity of demand. A seller should decrease the price of this good to increase total revenue. When demand is elastic, the percentage change increase in quantity demanded will be larger than the percentage change decrease in the price of the good.
