Question

Suppose that the total revenue received by a company selling basketballs is $600 when the price is set at $30 per basketball and $600 when the price is set at $20 per basketball. Without using the midpoint formula, identify whether demand is elastic, inelastic, or unit-elastic over this price range.

Answer 1

Answer: Demand is Unit - Elastic over this price range.

Step-by-step explanation:

When total revenue remains the same over various price level then the demand curve is unitary elastic.

Unit-Elastic demand - It depicts a demand curve which is perfectly responsiveness to changes in cost. That is, the amount of demand changes as indicated by a similar percentage changes in prices.

A demand curve with an elasticity of 1 is called as unitary elasticity of demand.
