Answer:
This good is a normal good and income-inelastic
Explanation:
Elasticity of demand measures the degree of responsiveness of quantity demanded to changes in price.
Elasticity of demand = (new quantity demanded - old quantity demanded) / ( new quantity demanded - old quantity demanded) / 2) / (New income - Old income ) / (old income + new income)/2)
(5 - 3) / (3 + 5)/ 2) / ( 33500-31900) / (31900+33500)/2) = 6.45
The coefficient of elasticity is greater than one, therefore, demand is income elastic.
This means that a small change in income leads to a greater change in quantity demanded.
A normal good is a good whose demand increases when income increases and falls when income falls.
Eating out is a normal good because her demand increased when income increased.
