A jacket is on sale for 20% off the regular price. The sale price is $50. What is the regular price of the jacket?
The regular price is
If the sale price is $50, and the sale is 20% off, that means the $50 represents the other 80% of the regular price—the part that you do pay. So then we ask ourselves, okay, $50 is 80 percent of... what? In math speak, that would be written as
Solving this for
We remind ourselves that the "percentage" symbol is just a shorthand for "divide this number by 100." The equation becomes
So the regular price is $62.50.
A general formula can be used for any regular price
As long as we know two of the three variables
The regular price is $62.50
[One more explanation as mentioned below]
Since the Jacket was sold 20% less than its original price, it means suppose the regular price of jacket is $100 so its 20% less is $80, but it sold in $50
If suppose the jacket was sold in $80 in place of it regular price $100, so what will be regular price if the jacket sold for $50
since, suppose sale price is $ 80 against its regular price $100
therefore what regular price will be, if jacket sold in $50
Hence answer is $62.5
