I need an equation
If I have an item that cost £1.00 and I increase the price by 20%, I get £1.20
What percentage to I have to decrease it by to get back to £1.00 |

Probably about, *scratches balls, ooh, I dunno, 375 to the power of 10, possibly? Then there'll be a deficit you'll have to make up..
Best to have a wank and a little break to think about things..
Hope that helps

"(1-1.2)/1.2 = -16.67%
What about the other way so if an item cost £1, you decrease it by 20% to make .80p how would you increase it back to £1
120%"
That simple? |

(1-0.8)/0.8 x 100 = +25%"

You're trying to remove 20p right. So you need to know what percentage 20p is of £1.20
So you go (20/120) x 100. That's the percentage you need to reduce by. |

No that's 96p."
You are, of course, correct |

"You're talking about to different amounts mate. To take a percentage from a figure you divide it by 1.(then the percentage you want to subtract). "
Its fine, Lacey and Marvel gave me the answer I was looking for |

Haha!! If you ever need to do it again it's just:
(New amount-original amount)/original amount x 100 |
