The price of a book is 4 pounds. In a sale the price is reduced by 30 percent. Work out the sale price

If we first calculate 30% of £4 to work out how much the price of the book has been reduced by.

10% of £4 is £0.40. We know 30% will be this value multiplied by 3. Therefore 30% of £4 is £1.20.

Now that we know how much the book has been reduced by we can simply do:

Original cost of book minus the reduction in price to find the new price of the book.

£4.00 - £1.20 = £2.80
