PED = 0.1571

Explanation:

The price elasticity of demand (PED) indicates how the quantity demanded change when the price changes. Is defined by this equation:

Price Elasticity of Demand = Percentage change in Q / Percentage change in P

In this case, the problem is giving percentage changes in Q but we must calculate the percentage change in price:

%Change in price = (p2-p1/p1) * 100 = ($4.09-$2.96) / $2.96 = 0.3817*100=38.17%

%Change in quantity is = - 6%

PED = - 6%/38.17%

In absolute value:

PED = 0.1571

If the PED is less than 1 then gasoline is considered as inelastic.
