In a sale, the original price of a bag was reduced by 1/5. The sale price of the bag is £29.40. Work out the original price.

  1. We currently have 80% of the original price and aim to find 100%.

  2. We know that 80% is equal to £29.40.

  3. Dividing £29.40 by 80 gives the value of 1% which is £0.3675.

  4. Multiplying this by 100 give the desired 100%. Therefore the original price of the bag was £36.75.
