Which cost metric is used to compare products across orders for price-conscious purchasers?

• A. Delivery speed
• B. Brand recognition
• C. Packaging color
• D. Cost of products per purchase unit

Answer: (D)

Price-conscious shoppers need a way to compare value when products come in different package sizes, orders, or quantities. The cost of products per purchase unit provides a single, standard measure of price by showing how much you pay for each unit of product, regardless of packaging. This makes it the best metric for cross-order comparisons because you can directly evaluate which option offers more product for the same dollar amount. For example, a 2‑unit package for $4 comes to $2 per unit, while a 4‑unit package for $7 comes to $1.75 per unit, making the latter the better value per unit. Other factors like delivery speed, brand recognition, or packaging color don’t quantify price per unit and don’t help compare cost across orders.
