What are the differences between elastic, inelastic, and unit elastic demand, and how do they impact the pricing and sales of a product?

Elastic demand means that a small change in price leads to a large change in quantity demanded. Inelastic demand means that a change in price has little impact on quantity demanded. Unit elastic demand means that the percentage change in price is equal to the percentage change in quantity demanded.

For pricing and sales, elastic demand typically leads to lower prices and higher sales volume, as consumers are more sensitive to price changes. Inelastic demand allows for higher prices with less impact on sales volume, as consumers are less sensitive to price changes. Unit elastic demand falls in between, with price changes having a proportional impact on sales volume.
