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:

  1. Discount Amount = 21 x 30 / 100
  2. = 21 x 0.3
  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:

  1. Final Price = Original Price – Discount Amount
  2. = 21 – 6.3
  3. = 14.7

So, after a 30% discount, the price you pay is 14.7.
