Simply put;
Price elasticity of demand = percentage change in quantity demand / percentage change in price
[tex]pEd[/tex] =[tex]\frac{percentage change in quantity}{percentage change in price, }[/tex] ; [tex]pEd[/tex] =[tex]\frac{Qd}{Pd }[/tex]
We were given that
Plugging in our values, we have that
1.20 =[tex]\frac{Qd}{0.15}[/tex]
Percentage change in quantity demanded[tex]Qd[/tex] =0.18 =18%
