Suppose that your demand schedule for pizza is as follows: Price Quantity of Pizzas Demanded Quantity of Pizzas Demanded (Dollars) (Income = $20,000) (Income = $24,000) 8 40 50 10 32 45 12 24 30 14 16 20 1.00 16 8 12 2.13 0.47 Using the midpoint method, your price elasticity of demand as the price of pizzas increases from $8 to $10 is if your income is $20,000 and if your income is $24,000. If the price of a pizza is $10, your income elasticity of demand is as your income increases from $20,000 to $24,000. However, if the price of a pizza is $12, your income elasticity is
