II-0. Suppose that your demand schedule for Movie is as below.
Price | Quantity Demanded when income =$10,000 | Quantity Demanded when income =$20,000 |
$5 | 50 | 60 |
$7 | 40 | 55 |
$9 | 30 | 50 |
$11 | 20 | 45 |
$13 | 10 | 40 |
Now the movie ticket price is $7 each. If the ticket price rises to $9 each,
Calculate the price elasticity of demand using midpoint method when your income is $10,000.
Step 1
How much is the change in quantity demanded?
What is the mid point of the quantities demanded between before and after change? Step 2 How much is the change in price? What is the mid point of the prices between before and after change? Step 3 What is the price elasticity of demand when the price changes from $7 to $9 and your income is $10,000? calculate - (a/b) / (c/d) What is the price elasticity of demand? |
Calculate the price elasticity of demand using midpoint method when your income is $20,000.
Step 1 -How much is the change in quantity demanded?
What is the mid point of the quantities demanded between before and after change?
Step 2 -How much is the change in price?
What is the mid point of the prices between before and after change?
