Due to political unrest coupled with the slow
recovery from pandemic, the global price of
petrol surged which led to an increase of price
per litre of petrol in your country from TK60 to
TK75.
After the price rise, the employees of the

curve at the new income level is P = 157 - 2Qp.
i. Calculate the income elasticity of demand
(YED).
Give your answer in two decimal places.
ii. Now assume that the increase in income (and
the subsequent shift of the demand curve) had
occured before the rise in price, then what would
the YED be?
