Which statement accurately reflects the relationship between revenue and price in the context of consumer surplus and willingness to pay?

• A. Total revenue is always greater than consumer surplus at any price.
• B. Total revenue increases as price rises, regardless of the quantity demanded.
• C. Total revenue is maximized when price equals the consumer's willingness to pay for every unit sold.
• D. Total revenue is equal to price multiplied by quantity sold, and changes in price can increase or decrease revenue depending on the elasticity of demand.

Answer: (D)

Verified step by step guidance

1. Step 1: Understand the definitions involved. Total revenue (TR) is calculated as the product of price (P) and quantity sold (Q), so \(TR = P \times Q\).
2. Step 2: Recognize that consumer surplus is the difference between what consumers are willing to pay and what they actually pay, representing the area under the demand curve above the price line.
3. Step 3: Analyze how changes in price affect total revenue by considering the price elasticity of demand, which measures how sensitive quantity demanded is to price changes.
4. Step 4: Recall that if demand is elastic (elasticity greater than 1), a decrease in price increases total revenue, while if demand is inelastic (elasticity less than 1), a price increase raises total revenue.
5. Step 5: Conclude that total revenue is not always greater than consumer surplus, nor does it always increase with price; instead, total revenue depends on both price and quantity sold, which are influenced by demand elasticity.
