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, can you tell whether demand is elastic, inelastic, or unit-elastic over this price range

Unit-Elastic

Explanation:

The elasticity of demand is the measure of responsiveness of demand against any change in the price. This show the ratio of change in quantity if price changes.

The demand is unit elastic because the revenue received after the change in price is the same as before the change. This means that equal ratio of decrease in price against equal ratio of increase in demand resulting no change in total revenue earned. Demand and price is perfectly responsive to the change in the same ratio.
