    Re: Percentages

    70 is 70% of 100. If we have the number 99 instead of 100, the new price will be 69.30. Is 69.30 70% of 99? Does any number reduced by 30%, becomes 70% of the original price?

    yep

    you start with 100% of the number and subtract 30%. So there is 70% left

    The ONLY stupid question is the one not asked ... get my drift?!

    Btw, remember that % or percent means "per hundred"; if you have 37 apples in a bag containing
    100 fruits, then the contents are 37% apples.
