The term "unit price" relates to a price to some common unit.

To determine the unit price, you can follow these steps:

1. Identify the price of the item or service you are interested in. For example, let's say you want to find the unit price of a bag of apples, and the total price of the bag is $5.

2. Determine the quantity or size of the item. In our example, let's say the bag contains 10 apples.

3. Divide the total price by the quantity or size. In our example, you would divide $5 by 10 apples.

4. The result of this division will give you the unit price. In our example, the unit price would be $0.50 per apple.

So, the term "unit price" refers to the price of a single unit or quantity of an item or service. It helps you compare prices and make informed purchasing decisions.
