Given parameters:

Original selling price = $84

Discounted Selling price  = $72

Unknown:

Percentage discount = ?

Solution:

To find the percentage discount;

  •   Find the discount amount
  •   Then find the percentage discount from this value when you place it over the original selling price

Discount = Original selling price  - Discounted selling price

               = $84 - $72

               = $12

Now,

  Percentage discount  = [tex]\frac{12}{84} x 100[/tex]   = 14.3%

The percentage discount is 14.3%
