Answer:
True
Explanation:
income elasticity of demand = % change in quantity demanded / % change in income
income elasticity of demand = 16.7% / 20% = 0.83, since it is positive, then they are normal goods but not luxury goods since the income elasticity of demand is ≤ 1.
If IED is negative, that means that a good is an inferior good, since the more you earn, the less you consume.
