Question 1

What is 20% off $100?

Accepted Answer

20% off $100 is $20 in savings, making the final price $80. To calculate: $100 x 0.20 = $20 discount, then $100 - $20 = $80 sale price.

Question 2

How do I calculate percentage off?

Accepted Answer

Multiply the original price by the percentage (as a decimal) to get the discount amount, then subtract it from the original price. For example, 30% off $50: $50 x 0.30 = $15 discount, $50 - $15 = $35 final price.

Question 3

What is the formula for percentage off?

Accepted Answer

The formula is: Sale Price = Original Price x (1 - Percentage / 100). Alternatively, Discount Amount = Original Price x (Percentage / 100), and Sale Price = Original Price - Discount Amount.

Question 4

How do I find the original price before a discount?

Accepted Answer

Divide the sale price by (1 - discount percentage / 100). For example, if you paid $60 after a 25% discount: $60 / (1 - 0.25) = $60 / 0.75 = $80 original price.

Question 5

What is the difference between percent off and percent of?

Accepted Answer

Percent off means the amount subtracted from the original price (e.g., 20% off $100 = $80). Percent of means the portion of the original (e.g., 20% of $100 = $20). They are complementary: 20% off means you pay 80% of the price.
