Thread: Calculate price before tax

    Calculate price before tax

    I used to know how to do this but, at 62, have forgotten. I know the final price; $4650.00. I know the shipping/handling charge is 7%. How do I calculate the cost BEFORE shipping/handling is added?

    Re: Calculate price before tax

    The value you now have is the original value with the 7% of the original value added.

    7% of an amount is [tex]\frac{7}{100}=0.07[/tex] of that amount

    So you can say

    [tex]4650=(1.07)original.[/tex]

    Therefore the original pre-Shipping&Tax amount is

    [tex]\frac{4650}{1.07}[/tex]
