In this lesson you’ll learn how to calculate the Discount Price of a pair of shoes.
I’m going to show you two simple methods for doing this.
Suppose you want to buy a pair of shoes and the original price of $95 has been discounted by 10%. How do you calculate the discount price?
Calculate the discount and take it away from the original price
So the amount of the discount is:
10% of 95
= 0.1 x 95
Then you subtract the discount amount from the original price:
So 95 – 9.5 = 85.5 which means the discount price is $85.50
Workout what percentage of the original price you will have to pay and then multiply that by the original price.
If the discount is 10% then what percentage of the original price will you pay?
Answer: 100% – 10% = 90%
So You will pay 90% of $95:
90% of $95
= 0.9 x 95
