Question: how to calculate percentage off cost?
Answer: Convert 25% to a decimal by dividing by 100: 25/100 = 0.25. Multiply list price by decimal percent: 130*0.25 = 32.50. Subtract discount amount from list price: 130 - 32.50 = 97.50. With the formula: 130 - (130*(25/100)) = 130 - (130*0.25) = 130 - 32.50 = 97.50. 25% off $130 is $97.50.
