We argon interested in how antiphonary consumers ar to pitch in price. Definition Price elasticity of beg (?) = Percentage transfer in touchstone Demanded Percentage Change in Price Due to the righteousness of prerequisite, the price elasticity of demand is always negative. Three cases Elastic Inelastic Unitary Elastic %? in P < %? in QD %? in P > %? in QD %? in P = %? in Q D |?| > 1 |?| < 1 |?| = 1 cognition Demand is elastic means that consumers are rather responsive to a change in price, i.e. they respond by ever-changing total demanded relatively more than the change in price. Demand is heady means that consumers are less responsive to change in price, i.e. they respond by mild change in amount demanded when price changes. Example: Steaks and potatoes example last calen dar calendar week Price of steaks increases by 33.33%, and price of potatoes increases by 20%. The wonder was whether quantity demanded of steaks rolls a lot more than that of potatoes, since the increase in price for steaks in greater. Now that you learn the concept of elasticity, you go bad on that if price elasticity of demand for both goods are finishing enough, then the statement is true.

However, if demand for steak is much more inelastic than demand for potatoes, although the price change is greater, the quantity demanded for steaks may drop less than that of potatoes.
