Suppose that your demand schedule for CD is as follows:

Price. Quantity demand (income =$10 000. Quantity demand (income =$12 000)

8 40 50

10 32 45

12 24 30

14 16 20

16 8 12

a) Calculate your price elasticity of demand as the price of CD 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 y

can you show all the workings please
