Answer:
1. 5.00
2. 3.75
3. 1.86
4. 1.22
Explanation:
The calculations are all in the attachment.
1. As the price elasticity goes from $14 to $16, the price of pizza becomes $5 at an income of $20,000
2. With income = $24000, if the price should move from $14 to $16, the price elasticity of demand is 3.75
3. With the price of pizza at $10, the income elasticity of demand as income rises from 20000 to 24000 = 1.86
4. If we have price if pizza as 24 dollars, with income rising from $20000 to $24000, then the income elasticity of demand = 1.22
