What is the total after a 10% discount on £100?

The total after a 10% discount on £100 is £90.

To work out the total after a 10% discount on £100, you first need to understand what a percentage discount means. A 10% discount means you are reducing the original price by 10%. To find 10% of £100, you multiply £100 by 0.10 (since 10% is the same as 10/100 or 0.10).

So, £100 × 0.10 = £10. This £10 is the amount of the discount.

Next, you subtract the discount from the original price to find the final price. So, £100 - £10 = £90.

Therefore, after applying a 10% discount to £100, the total amount you would pay is £90. This method can be used for any percentage discount and any original price. Just remember to convert the percentage to a decimal by dividing by 100, multiply it by the original price to find the discount, and then subtract that discount from the original price.
