Question

At the beginning of this year, daily consumption of gasoline in the US amounted to 344 million gallons. It is estimated that for every 10% increase in the price of gasoline, quantity demanded falls by 1.9%. By the end of this year, the price of gasoline is expected to increase by 40 cents from $ 3.05 per gallon. Based on this information, what is the expected quantity demanded (QD) for gasoline at the end of this year

Answer 1

335.43 million gallons

Step-by-step explanation:

price elasticity of demand (PED) = % change in quantity demanded / % change in price

PED = -1.9% / 10% = -0.19, very inelastic

expected price increase $0.40

% change in price = ($3.45 - $3.05) / $3.05 = 13.11%

% change in quantity demanded:

-0.19 = D / 13.11%

D = 2.49%

quantity demanded will decrease by 2.49%, from 344 million gallons to 335.43 million gallons
