How do you find the cost per item if 4 items cost £12?

The cost per item is £3.

To find the cost per item when 4 items cost £12, you need to divide the total cost by the number of items. This is a straightforward division problem. You start with the total cost, which is £12, and the number of items, which is 4.

Using the formula:
\[ \text{Cost per item} = \frac{\text{Total cost}}{\text{Number of items}} \]

Substitute the given values into the formula:
\[ \text{Cost per item} = \frac{£12}{4} \]

When you divide £12 by 4, you get £3. This means each item costs £3.

This is a useful skill in everyday life, whether you're shopping, budgeting, or even planning events. Understanding how to break down costs helps you manage your money more effectively.
