What is 20% off of 500?
This is a common calculation, and here's how to solve it, explained in a way that's easy to understand:
Understanding Percentages
A percentage is a fraction of 100. 20% means 20 out of 100, or 20/100, which simplifies to 1/5. So, finding 20% of a number means finding one-fifth of that number.
Method 1: Finding 20% and Subtracting
-
Calculate 20% of 500: To do this, multiply 500 by 0.20 (which is the decimal equivalent of 20%).
500 * 0.20 = 100
-
Subtract the discount from the original price: Subtract the 20% discount (which is $100) from the original price of $500.
500 - 100 = 400
Therefore, 20% off of 500 is 400.
Method 2: Calculating 80% Directly
Since taking 20% off leaves 80% remaining, you can calculate this directly:
-
Calculate 80% of 500: Multiply 500 by 0.80 (the decimal equivalent of 80%).
500 * 0.80 = 400
Therefore, 20% off of 500 is 400. This method is often quicker.
In short: After a 20% discount, the final price is $400.
