Figuring Percentage of IncreaseDate: 09/05/2001 at 10:41:15 From: Carmy Subject: Percentages I am looking for help on calculating the percentage of, say a population increase. In 1990, Allen County, Kansas, had 14,385 people. Now, in 2001, it contains 14,905 people. How do I calculate the increase, using a percentage? Date: 09/05/2001 at 15:17:20 From: Doctor Ian Subject: Re: Percentages Hi Carmy, The formula for percentage increase is new value - old value --------------------- * 100 old value For example, if something increases from 15 to 18, the percentage increase is 18 - 15 3 ------- * 100 = -- * 100 = 0.2 * 100 = 20% 15 15 Can you follow the same steps to solve your own problem? - Doctor Ian, The Math Forum http://mathforum.org/dr.math/ Date: 09/05/2001 at 20:25:13 From: (anonymous) Subject: Re: Percentages Thank you, I have now figured out the problems.
