How do you calculate the total cost of 10 items at £1.75 each?

To calculate the total cost of 10 items at £1.75 each, multiply 10 by £1.75.

When you need to find the total cost of multiple items, you simply multiply the number of items by the cost of one item. In this case, you have 10 items, and each item costs £1.75. So, you perform the multiplication: 10 × £1.75.

Let's break it down step-by-step. First, write down the multiplication:

\[ 10 \times 1.75 \]

To make it easier, you can think of £1.75 as £1 + £0.75. So, you can split the multiplication into two parts:

\[ 10 \times 1 = 10 \]
\[ 10 \times 0.75 = 7.5 \]

Now, add these two results together:

\[ 10 + 7.5 = 17.5 \]

Therefore, the total cost of 10 items at £1.75 each is £17.50.

This method works for any number of items and any price per item. Just remember to multiply the quantity by the unit price, and if needed, break down the multiplication into simpler parts to make the calculation easier. This approach ensures you get the correct total cost every time.
