A retail manager is analyzing the relationship between the unit price $p$ of a product and its daily sales volume, or demand $d$. If the manager determines that the demand varies inversely with the price, which formula correctly represents this relationship using a constant of variation $k$?

In a corporate pricing model where product demand $d$ is inversely proportional to unit price $p$, the constant of variation $k$ is determined by calculating the product of the demand and the price ($k = d \cdot p$).

A retail analyst uses an inverse variation model to predict how changes in unit price will affect the daily quantity of products sold. Match each component of the mathematical model with its correct role or definition.

A marketing analyst is using an inverse variation model to predict how changes in unit price will affect the daily demand for a product. To determine the new demand after a price change, arrange the following procedural steps in the correct order.

A retail analyst is modeling the relationship between the unit price of a product ($p$) and its daily demand ($d$). Having established that the demand is inversely proportional to the price, the analyst uses the formula $d = \frac{k}{p}$. In this inverse variation model, the term $k$ represents the ____.
