Suppose that your demand schedule for dvds is as follows: price quantity demanded (income = $10,000) quantity demanded (income = $12,000) $8 40 dvds 50 dvds 10 32 45 12 24 30 14 16 20 16 8 12 a. use the midpoint method to calculate your price elasticity of demand as the price of dvds increases from $8 to $10 if (i) your income is $10,000 and (ii) your income is $12,000. b. calculate your income elasticity of demand as your income increases from $10,000 to $12,000 if (i) the price is $12 and (ii) the price is $16.
