Thanks. I found this super helpful. But is there any way to check if your answer is correct? Like estimating.. Im in fifth grade, so whenever we do something in math we most likely check our answers to see if there correct. Aha,but thanks again. http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=58078#Comments http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=58078#Comments Mon, 04 Feb 2013 06:31:12 GMT Kacy sampleCategory xxxxx http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=57667#Comments http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=57667#Comments Thu, 24 Jan 2013 03:06:07 GMT Memii sampleCategory Thanks I was shopping today and got super stuck . so I decided to google it you camed up thanks again . http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=52420#Comments http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=52420#Comments Mon, 16 Jul 2012 06:19:56 GMT Lisa sampleCategory I am thrilled Math Dude gave the 10% starting point....I have been out of school for years....always had a hard time with math anyway, got it and tested well (had a gifted teacher..waited for me to get it before he would move on ) but wouldn't retain it afterward..this was simple..something I needed and more importantly could understand right away. Had good grades in school but, worked hard for them..found later I had learning disability in Math..thank you once more for the information. http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=49857#Comments http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=49857#Comments Sun, 15 Apr 2012 02:21:08 GMT Meratvforum sampleCategory Excellent post, but as far as strategies go, wouldn’t it be better to use SnapNames and Enom initially, since you can get into Pool’s Challenger auction if someone else is using them to snap up the domain. http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=42554#Comments http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=42554#Comments Wed, 21 Sep 2011 14:36:13 GMT PeteSa sampleCategory Thanks, that was a great article on easy ways to calculate sales prices. I realized that I utilize the 10% method a lot. I hope to share this article with my 11 year old son. While very handy; technically the “what you will be paying” method is a three step process also. (Step 1) 30%-100=70 (Step 2) 70. to 7.0 (Step 3) 7x4=28. “10% Method”: (Step 1) 40. to 4. (Step 2) 3x4 =12 (Step 3) 40-12=28 http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=30404#Comments http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=30404#Comments Fri, 14 May 2010 16:14:28 GMT Math Dude sampleCategory Thanks, Marilyn. You are certainly correct that the problem can be solved in a single step. However, one of the points of the article is to show that the relatively simple skill of calculating 10% of a number can open the door to solving a bunch of problems (not just the one described here). In fact, there's a companion Math Dude article about using 10% as a starting point for calculating restaurant tips. In practice, going through the thought process you describe is probably faster...especially once you've got the hang of it. But the more general skill of calculating 10% and figuring out how to use it in a variety of problems is useful too. The beauty of math is that once you're comfortable with the ideas, you can use them as tools to devise your own solution methods...exactly as you've done! That's great! http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=30330#Comments http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=30330#Comments Wed, 12 May 2010 00:04:58 GMT Marilyn sampleCategory Why make a two step process of it? If you have a $40 shirt in hand and want to know the price you will pay at 30% off just multiply by 70% because you will be paying 70% of the original price. 7 times 40 is $28. The important part is what you pay, not what you save. http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=30327#Comments http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx?commentid=30327#Comments Tue, 11 May 2010 20:09:42 GMT Fri, 22 Mar 2013 00:14:12 GMT http://mathdude.quickanddirtytips.com/how-to-use-percentages-to-easily-calculate-sales-prices.aspx feedback@quickanddirtytips.com (Managing Editor) feedback@quickanddirtytips.com (Webmaster) en-us
