Question 1

How do I calculate a discount?

Accepted Answer

Multiply the original price by the discount percentage divided by 100, then subtract from the original price. For example, 20% off $50: $50 - ($50 × 0.20) = $40.

Question 2

How do I calculate the sale price after multiple discounts?

Accepted Answer

Apply each discount sequentially. For example, 20% off then 10% off $100: First discount: $100 × 0.80 = $80. Second discount: $80 × 0.90 = $72.

Question 3

What is the difference between 'percent off' and 'dollars off'?

Accepted Answer

'Percent off' is a relative discount based on the price — e.g. 20% off $50 = $10 savings. 'Dollars off' is an absolute discount — e.g. $10 off any price.
