Round your answer to two decimal places. income elasticity of demand:Units This good isa normal good. an inferior good. a luxury good.

4.20 and normal good

Explanation:

The computation of the income elasticity of demand is shown below:

= (change in quantity demanded ÷ average of quantity demanded) ÷ (percentage change in income ÷ average of quantity income)  

where,  

Change in income would be

= Q2 - Q1

= 109,500 - 102,300

= 7,200

And, average of income would be

= (109,500 + 102,300) ÷ 2

= 105,900

Change in quantity demanded would be

= 4 - 3

= 1

And, average of quantity demanded would be

= ($4 + 3) ÷ 2

= 3.5

So, after solving this, the income elasticity of demand is 4.20

Since the elasticity comes in positive which means the good is a normal goods

i believe the answer would have to be a dependable person
