(12C Platinum) Successive Discounts

[Gamo]

Successive discount is the discount offered on the discount.
It is similar to compound interest (interest on interest).

A company many offer two trade discount, 20% and 5%.
One customer may be entitled to a 20% discount and another
will get 5%, depending on status (jobber, wholesaler, retailer, etc.), and
a third customer of different status will receive 20% and 5%.

X = Price
Y = Discount %
Z = Discount %

Selling Price = X - [Y + Z - (Y*Z / 100)] * X
