Suppose that during the past year, the price of a laptop computer rose from $2,750 to $2,880. During the same time period, consumer sales decreased from 446,000 to 321,000 laptops. Original New Average Change Percentage Change Quantity -32.59% /-16.3%/-306.8% Price 4.62% /2.31%/2165.38% Step 1: Fill in the appropriate values for original quantity, new quantity, original price, and new price. Step 2: Calculate the average quantity by adding the original quantity and the new quantity, and then dividing by

Step 1: Fill in the appropriate values for original quantity, new quantity, original price, and new price.
Step 2: Calculate the average quantity by adding the original quantity and the new quantity, and then dividing by two. Do the same for the average price.
Step 3: Calculate the change in quantity by subtracting the original quantity from the new quantity. Do the same for the change in price.
Step 4: Calculate the percentage change in quantity demanded by dividing the change in quantity by the average quantity. Do the same to calculate the percentage change in price.
Step 5: Calculate the price elasticity of demand by dividing the percentage change in quantity demanded by the percentage change in price, ignoring the negative sign.
Using the midpoint method, the elasticity of demand for laptops is about_____0.14/3.53/7.05/14.11
