How do I calculate a 20% discount?

Multiply the original price by 0.20 (20/100) to find the discount amount, then subtract from the original. Example: $100 × 0.20 = $20 discount, so $100 - $20 = $80 final price.

What is 30% off $150?

Discount amount: $150 × 0.30 = $45. Final price: $150 - $45 = $105. So 30% off $150 is $105.

How do I calculate multiple discounts?

Apply discounts sequentially. For 20% then 10% off $100: First discount: $100 - ($100 × 0.20) = $80. Second discount: $80 - ($80 × 0.10) = $72 final price.
