How to Calculate 30% Off $21
When an item originally costs $21, applying a 30% discount means you’re reducing the price by a specific amount. Here’s how to calculate it step by step:
Step 1: Find the Discount Amount
Use the percentage discount formula:
Discount Amount = Original Price x Discount Percentage / 100
Substituting the values:

- = 21 x 0.3
- = 6.3
So, a 30% discount on $21 saves you 6.3.
Step 2: Calculate the Final Price
Now, subtract the discount amount from the original price:
- Final Price = Original Price – Discount Amount
- = 21 – 6.3
