## Math Formula

The formula for calculating the final price is:

**FP = OP – (OP * PO/100)**

- FP = Final price
- OP = Original Price
- PO = Percent off

## Solved problem

Example – Let’s say you have a pair of shoes with an original price of $80, and you want to apply a 20% percent off to them. then calculate the final price?

Given value,

Original price = $80, percentage off = 20%

**Final Price = Original Price – (Original Price * Percent off/100)**

Final Price = $80 – ($80 × 20 / 100) = $80 – ($16) = $64

So, after a 20% discount, the final price of the shoes would be $64.
