D

Total revenue always decreases for inelastic demand

Understanding the Answer

Let's break down why this is correct

Answer

When the price of a product falls, the total revenue it generates depends on how sensitive buyers are to that price change. If demand is elastic, the drop in price leads to a proportionally larger increase in quantity sold, so revenue goes up. If demand is inelastic, the quantity sold rises only a little, and the lower price outweighs the extra sales, causing revenue to fall. When the elasticity is exactly one (unit elastic), the extra units sold exactly offset the lower price, so revenue stays the same. For example, if a shirt’s price falls from $10 to $8 and sales rise from 100 to 200 units, revenue rises from $1,000 to $1,600 because demand is elastic.

Detailed Explanation

When the price falls, buyers buy more. Other options are incorrect because Some think revenue falls when demand is elastic, but that is wrong; Revenue does change with elasticity.
