How to Calculate 20% Off $21
When an item originally costs $21, applying a 20% discount means you’re reducing the price by a specific amount. Here’s how to calculate it step by step:

Use the percentage discount formula:
Discount Amount = Original Price x Discount Percentage / 100

So, a 20% discount on $21 saves you 4.2.
Step 2: Calculate the Final Price
