How to Use

Run the script and follow the prompts.

• If the discount is 20% or more, the final price is shown.
• If the discount is less than 20%, the original price is shown with a message.

Example run:

• Enter the original price of the item: 120
• Enter the discount percentage: 25
• Output:
  • The final price after applying the discount is: $90.00

Example where no discount is applied:

• Enter the original price of the item: 100
• Enter the discount percentage: 15
• Output:
  • No discount applied. The original price is: $100.00
