Relationship between Demand Curve Slope and Price Elasticity of Demand
The slope of the demand curve is mathematically linked to the price elasticity of demand (varepsilon). This relationship can be expressed by the formula: . This equation shows how the rate at which a firm must lower its price to sell more units (the slope) is determined by the price, quantity, and consumer responsiveness (elasticity) at that point on the demand curve.

A company sells a product at a price of $100 per unit, with current sales of 500 units per week. At this specific price and quantity, the price elasticity of demand is estimated to be 2.0. A consultant suggests that the company should adjust its strategy to operate at a point on the demand curve that is 'steeper' (i.e., has a slope with a larger absolute value). Assuming the goal is to be in a market segment where consumers are more responsive to price changes, which of the following statements correctly analyzes the consultant's advice?
