Click to show formula

$E^{d}_{p_{x}} = \frac{\%\Delta Q^{d}_{x}}{\%\Delta P_{x}}\ or\ E^{d}_{p_{x}} = (\frac{\Delta Q^{d}_{x}}{\Delta P_{x}})\times (\frac{P_{x}}{Q^{d}_{x}})$

• $E^{d}_{p_{x}}$ – own-price elasticity of demand
• $Q^{d}_{x}$ – quantity demanded of good "X"
• $P_{x}$ – price per unit of good "X"
