Answer:
Income Elasticy =2
Explanation:
To calculate the income elasticity of demand by the midpoint method, we use the following formula:
Income Elasticy = Change in qd / (old qd - new qd / 2)
And this result is in turn divided by
Change in income / (old income - new income / 2)
Therefore, we obtain:
= 1 / ( 20 - 19 / 2)
= 1 / 0.5
= 2
And
= 14,000 / ( 44,000 - 30,000 / 2 )
= 2
The final result is
Income Elasticity = 2 / 2
= 1
The outfits are a normal good, because as the quantity of income decreases, the quantity demanded for it decreases too.
