Sale Percentage Discounts

Difficulty: Rating:

GCSE Marks:

GCSE Text: The table below shows three items that have been discounted in a sale. For each item you can see their original pre-sale price, and the price being charged in the sale.

a) For each of the three items, by what percentage has the original price been reduced?

b) Which item has the highest percentage of reduction from the original price, and therefore represents the best deal in the sale?

Suggestions:
This is a firm favourite when teaching or recapping percentages, and it enables students to understand the application of percentage calculations. It is normally takes a class 3-4 minutes to complete this, but often students needs to be reminded to find the amount of reduction first, and then use that in their percentage calculations.

Extension Ideas: Teachers could extend the learning by considering:

If you bought two chocolate oranges in a ‘buy one get one free’ deal, by what percentage has each orange effectively been reduced?

If you bought two boxes of chocolate in a ‘buy one get one half price’ deal, by what percentage has each box effectively been reduced?
