Answer:
Income elasticity of Demand is 4.51
a normal good and income-elastic
Explanation:
Percent change in quantity = [( q2- q1 ) / (( q2+q1) /2)] *100
= (4-3)/ 4+3/2 *100
=28.57%
Percent change in Income = [( y2- y1 ) / (( y2+y1) /2)] *100
= ($109,500- $102,750) / $109,500- $102,750/2
= 6.36%
YED= % change in QD / % change in y
= 28.7% / 6.36%
= 4.51
A normal good is a good that experiences an increase in its demand due to a rise in consumers' income. Demand for a good is elastic when a change in price has a relatively large effect on the quantity of the good demanded and elasticity value is greater than 1.
