Answer:
The answer is YED for concert tickets = 20%/ 20% = 1
YED for bus rides = -20% / 20% = -1
Explanation:
income elasticity of demand (YED) = % change in Quantity demanded / % change in income
% change in income= (240-200) / 200 * 100= 20%
YED for concert tickets = 20%/ 20% = 1
YED for bus rides = -20% / 20% = -1
The income elasticity of demand for concert tickets and bus rides is unitary which means the rise in income is proportionate to the increase in the quantity demanded.
