Suppose that your demand schedule for DVDS is a follows:
Quantity demanded
(income = $10,000)
Quantity demanded
(income = $12,000)
Price

a) Use the midpoint method to calculate the price elasticity of demand as the price of DVDS
increases from $8 to $10, given that your income is fixed at $10,000. Show work.
b) Use the midpoint method to calculate the income elasticity of demand as your income increases from
$10,000 to $12,000, and the price is fixed at $12. {hint: (Q2-Q1)/[(Q;+Q1)]/2 ;where I is Income}
(Iz-I1)/[(I+I1)]/2
