help finding profit for previous year
Hi my first posting...

Looking at the example below can someone tell me were the value 1.3 same from. Thanks...

If the increase from 2006 to 2007 was 30%, how much profit was made in 2006?

Year Profit (millions)
2007 25
2008 30

25 by 1.3, giving ,25 / 1.3 = 19.23
to 2 decimal places. Hence the 2006 profit was approximately 19m.

Apprantley 1.3 is standard when calculating for previous year

im not sure what you mean by "standard".

1.3 = 130%, which is a 30% increase

Re: help finding profit for previous year
So if 30% increase then 30 + 100 = 130%. 130 / 100 = 1.3. Can you explain the theory side because I do not understand. Why 130 / 100 to get 1.3

Example:

x : 1638

1638 is 17% higher than x; what's x?

x + .17x = 1638
1.17x = 1638
x = 1638 / 1.17 = 1400
