1) Over this price range ($4 to $5), the elasticity of demand for this beer is positive but less than one.
2) The degree of elasticity for this beer is 0.8.
3) A 1% change in the price of this beer led to a change in quantity demanded of 0.8%.
4) The total revenue when the price was raised by the local drinking establishment changed by $0.
The elasticity of demand refers to the sensitivity of demand to economic factors, for example, price.
This index is known as price elasticity. Price elasticity is computed by dividing the change in demand (or supply) by the change in price.
The old price of draft beer = $4
The new price of draft beer = $5
Increase in the price of draft beer = $1 ($5 - $4)
Percentage increase in price = 25% ($1/$4 x 100)
Sales units under old price = 5,000
Sales units under new price = 4,000
Decrease in sales units = 1,000 units (5,000 - 4,000)
Percentage decrease in sales units = 20% (1,000/5,000 x 100)
Degree of elasticity of demand = Percentage Change in Quantity/Percentage Change in Price
= 0.8 (20%/25%)
