How to Calculate 15% Off $21
When an item originally costs $21, applying a 15% 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

- = 3.15
So, a 15% discount on $21 saves you 3.15.
Step 2: Calculate the Final Price
Now, subtract the discount amount from the original price:
