What is a unit price?

• A. The price charged after applying discounts.
• B. The price charged per individual unit of a good or service.
• C. The price charged for shipping per order.
• D. The price charged per total quantity.

Answer: (B)

Unit price is the amount charged for each individual unit of a product, which lets you compare value when items come in different sizes or packaging. It is calculated by dividing the total price by the quantity (for example, price per litre or per item). This makes it easier to see which option gives you more value per unit.

For instance, if a 1‑litre bottle costs £1.80 and a 2‑litre bottle costs £3.00, the unit prices are £1.80 per litre and £1.50 per litre respectively, so the larger bottle offers better value per unit. The other phrases refer to different costs (such as discounts, shipping charges, or total price per quantity) and do not describe the cost per single unit.
