Demand Elasticity: 66%
Price Elasticity: -11%
Using the price elasticity of demand above, if Starbucks decreases its price by 10 percent, what would happen to the quantity demanded for Starbucks coffee?
EP = 66% / -11% = -6
We know:
EP = % change in quantity demanded / % change in price
% change in quantity demanded = EP * % change in price
= -6 * -10 [Here, -10 means price decreases by 10%]
= 60%
Thus, the quantity demanded for Starbucks coffee increases by 60%.
