Question 1

How do I calculate a discount price?

Accepted Answer

Multiply the original price by the discount percentage, then subtract from the original price. Formula: Sale Price = Original Price × (1 - Discount% / 100). Example: $80 with 25% off = $80 × 0.75 = $60.

Question 2

How do I find the original price from a sale price?

Accepted Answer

Divide the sale price by (1 minus the discount rate). Formula: Original Price = Sale Price ÷ (1 - Discount% / 100). Example: $60 at 25% off → original = $60 ÷ 0.75 = $80.
