Finding Sale PriceDate: 03/01/2002 at 10:33:19 From: Amnesty Subject: Understanding and using percent Hello, We are studying how to find the sale price by subtracting the discount from the regular price. Can you help me? Date: 03/01/2002 at 12:28:22 From: Doctor Peterson Subject: Re: Understanding and using percent Hi, Amnesty. We have a number of answers to questions in this area, which you can find by going to our search page http://mathforum.org/mathgrepform.html and entering the key words from your question, price discount percent Most of these deal with the reverse problem, finding the original price when you know the sale price. Here's a sample problem in the forward direction: If the regular price is $8.99, and the item is being sold at 30% off, what is the sale price? Well, 30% of $8.99 means 30/100, or 0.30, times $8.99: 0.30 * 8.99 = 2.697 That much is being taken off the price, so the sale price is $8.99 - $2.697 = $6.293 which would be rounded down to $6.29. Another way to do this would be to recognize that if 30% is being taken off, then what's left is 70%; so you can just multiply $8.99 by 70% to get the sale price: 0.70 * $8.99 = $6.293 If this isn't quite the kind of problem you are doing, or if I haven't helped where you need help, please write back and show me a specific problem and how you tried to do it. That way I can actually help you. - Doctor Peterson, The Math Forum http://mathforum.org/dr.math/ |
