Imagine finding a cool toy rocket that costs 6 dollars, but it has a bright red tag that says 2 dollars off!
A discount is a reduction in the original price (retail price) of an item, resulting in a lower final sale price.
Sale Price=Original Price−Discount Savings

To find the sale price, subtract the discount savings from the starting amount: Sale Price=Original Price−Discount Savings For the rocket: 6−2=4 dollars.
What if the store sign doesn't give a dollar number, but says half off instead?
Half Off Discounts
When an item is half off, you share the price into two equal groups and pay only one group.
📊Interactive diagram
If a board game costs 8 dollars and is half off, you split 8 into two equal piles of 4 and 4.
You save 4 dollars, so your new sale price is just 4 dollars!
What does it mean when a sign uses the percent symbol and says 10% off?
